Look at the chart below and quickly say the color, not the word. This prooves how our brain uses each side of the brain for different action: your right side of the brain want’s you to say the color, but the left side insists on reading the word!

    When I was little I had a large page with this on it (Mom cut it from some magazine) and I would spend all of my free time trying to do it. I finally said all of the colors around age 10 or so, and to this day I can still do it.

  2. Rammy says:

  7. Oldwize1 says:

    that was simple…

  8. Drew says:

    Took me less than 20 seconds without a mistake. I used to be lousy at stuff like that as I’m a word orientated person.

  9. Archie411 says:

    It was ok until I got to the last purple yellow
    I suddeny forgot what purple is called

  10. thats easy says:

    the last time i seen this was in primary school!! brings back memories haha, i was the only 1 in the class who could do it, even the teacher was freaked out! turns out i got autism and cant leave me house, oh well, eggs

  11. th says:

    the trick to doing it correctly a quickly is to blur your eyes, because you will just see a blurry blob.

  12. T H O says:

    just cross your eyes and it is no problem

  13. Hai says:

    ha! THO’s idea is funny! and works!!

  14. mina says:

    haha you’re right THO and Hai, but that’s just cause it get’s all blurry…

  15. Mike says:

    The trick is to not read the words. Just look at the last letter of each word and say the color of the letter.

  16. kitty says:

    I stil can’t. it is funny tough. xD

  17. purple..oh. u no da rest says:

    omg dis is like so kool mum sez she could do dis wen she woz young and gesswot? i can 2!!!

  18. biclops says:

    bah! that last one always gets me

  19. Rayne says:

    Is the last “yellow” supposed to be blue or purple?

  20. Rayne says:

    Oh, wait… It’s purple. I just wasn’t sure because there is only one word with purple colouring.

  21. smilely says:

    wicked easy

  22. M 2 the H O says:

    its cheatin if you blur your eyes, i got it 1st time 2
    and georgina ur right, its alot easy 4 girls in many brain tests. girls r even better at findin stuff in the frige than guys. proven. boys tend 2 look 4 the word butter writtin on sumthin while girls remember exactly what shape the butter is and find it much quicker,
    exeption 2 all the sissy guys (and gay 1s)

  23. Spença says:

  37. Purple maya says:

    Very easy…

  38. smarty says:

    2 EASY way 2 easy

  39. Anonymous says:

    I would imagine that people who are better/faster readers would have a more difficult time with this problem. This puzzle is easy for me because I can force myself to focus on a single letter and not read the entire word – but my sister (who is like a super speed-reader – an entire 300 pg book in one evening) found this to be hard.

  40. Wildo says:

    It’s easy if you know how to read

  41. 2 good 4 this says:

    me and my friends used to do that all the time.I was always the best one to do that. this page was the easiest one ever my 7 year old brother can do it too. thats how easy that was. any 1 who can’t do that is a looser!!!

  42. Anonymous says:

    try this with the color names written in a non common language for you, like norwegian (for me)… our brain cheats us

  43. Anonymous says:

    we did this in maths

  46. molly says:

    Wow that was well easy!! it took me praticly like 5 secs. i found it easier doin it backwards. and yes anonymous we are well better and multi tasking cos we have smarter brains so ha! I REST MY CASE! thankyou

  47. molly says:

    i found that in like 5 secs its well easy! reading it backwards is the easiest way for me lol! :)

  48. qwertyuiopasdfghjklzxcvbnm says:

    iv dne smthing lke tht on a game clled brain age

  49. aaron says:

    Women are better at multitasking because they can’t focus on one thing at a time. Besides, the easiest way is not backwards, the best way is to look at only one letter.

  50. Anonymous says:

    well i did it first time cool!!!
    then realised i had miss read what you were ment to do so was just reading the words!! doh!!
    so tried again (the right way) and struggled, but was proud as i had a brain injury 3 yrs ago! and did better than i thought

  51. Zc says:

    It has nothing to do with being a girl! It matters about how developed your brain is. Lefties tend to do this easier that righties!

  52. Mike says:

    you guys are ssooooo stupid, girls arn;t smarter, which by saying they are, makes them look stupider then what most people think. and lefties do not do it better, don’t be retarded just becuase you can’t use your right hand like everyone else

  53. Anonymous says:

    it was for me really easy becouse i am from another country ;d;d

  54. Trevor says:

    Well considering these are always easy for me I seem to be able to control my thinking a little better than some plus I have an IQ of 142 so I don’t get confused by whats there… still always a good test every now and then

  55. Kira says:

    Ohhh i’ve done this thing before, only i was timed!

  56. Anonymous says:

    that was sooo easy !

  57. wondershaman says:

    i have done way too many of these for it to phase me, but i like the concept.

  58. Anonymous says:

    it was pretty easy eaven though i had to stop befor evry black letter

  59. Lugoffo says:

    it’s really easy when your primary language is not english :P

  60. Emma says:

    i can’t be bothered looking back to see what ur names r but those of u who said “it’s just like READing” and “it’s easy if u can READ” should go back and try READing the instructions

  61. JK says:

    Maybe girl’s brains ARE better. I mean, I did that with no errors in like 30 secs with only a few short gaps, no mistake. My sis and bro…well…my sis did better and even though their eyesights are about the same and she was farther than him, he still didn’t do it all the first time. But I think he didn’t understand when I told him to read the colors.

  62. Anonymous says:

    :P I just take off my glasses to cheat

  63. guitarboy says:

    wow this is easy i think the people saying girls can use both sides of their brains, this is not true, some people can bu i think boys have more math and girls have more reading. personaly i thinnk i am a really good reader and pretty good at math, and im a boy. but anyway i did it the first time no mistakes in 8 seconds. its kinda easy, just focuse a lttle

  64. Anonymous says:

    Lol…acting like a girl ( being a sissy or gay) won’t make it any easier. I’m a guy and i could do this quite easily after a few seconds. But I don’t think anyone can do it quick and on their first try. Boys are better than girls at things the same way girls are better than boys at things.

  65. Anonymous says:

    It’s easy.Focus below the word.

  66. Anonymous says:

    stop braggin’ people
    uhm it was kinda hard
    i messed up about twice
    if you got it the first time, good for you!
    not everyone is as smart as you

  67. Teengirl says:

    It is cheating if you blur your eyes or things like that. It just depends on your ability to focus something that you rarely do. When you read you focus on the word not the color.

  68. Anonymous says:

    Just like Archie411, I forgot what purple was called, so I said orange. lol it doesn’t say or look orange….I must be getting dumber. Btw, I did a science fair project on this. It’s called the Stroope Effect.

  72. Maddie says:

    I don’t think I got the right answers… I am color-blind (and yes I am a girl) and all I could see was the green and blue and black and purple. Was that wrong?

  73. the technogirl says:

    try to go slightly crosseyed until you cant see the words, just the color. Read the color. easy.

  74. Anonymous says:

    It’s easy because I’m not english

  75. ki monishee says:

    hello and i agree with what annie had said ummm get tougher stuff anyway it wuld be more of a challenge not easy

  76. katelyn says:


  77. Entenuki says:

    If you can’t read, you can do this easier.

  78. India7121 says:

    I think Zc meant people who use the left side of their brain more than their right.

  79. erica :] says:

    OUCH! mike, theres no need to be harsh! god! calm down!

  80. grace says:

    some of u are sexists cause its not about whether you are a boy or girl just about how much u can focus

  81. Mike says:

    Six seconds. I can read, am not color blind, and looked right at each word in question. I happen to be good at this, but it has nothing to do with one’s IQ.

  82. petting a dragon says:

    i did my science fair on this
    it is called the stroop effect
    it was invented by jonh ridley stroop in 1935
    It is a factor that demonstrates the influence of inference on a person’s reaction time.
    it occurs because people actually read words faster then they con recognize colours, so their brain develops a preconceived idea of what the colour will be. but when the colour turns out to not match that idea, their brain receives conflicting signals. the brain must actually deal with those signals and chose the correct one.
    it is also true that is you read slowly (and have not have practice with this) then you will complete this faster, as the strength of those signals is lessened

  83. amanda says:

    really, some girls and boys are equal so shut up you retards. if you think you are sooooo smart then you really aren’t, and that was very easy and i’m 12.

  84. Edward Strepp says:

    Whilst we are on subject of reading and
    visual cognizance,
    PROVE has just the one “O”. I would have
    mentioned it earlier but this IS my 1st visit.

  85. Hey Ahn says:

    Used to find this really confusing but surprisingly, on this site, I found it a lot easier. I say just focus on the color of the words, not on the letters. ;>

  86. stuart says:

    These ones are fairly easy you can either blur your eyes or just read it so fast that the words loose their meaning and it just becomes a colour.

  87. akiel says:

    lefties can do it better cuz they use their right brain more than the left

  88. Chris says:

    Its so easy!!
    first try got it, its just hard to say the colour the word is, like if it says yellow and its green,
    i tryed to do
    green instead, but i failed XD

  89. Radical Bombs says:

    it was hard because i tried so hard to have the colour in my mind and not the colour of the word

  90. cheyenne says:

    im good i could say it all pretty quick without hesitating..imma girl and yes,mayb just may b girl r better. cuuuuzzz..
    im 11 and alittle immature as u can c from what i just said about boyz

  91. cheyenne says:

    its waaay harder to say the real color then the word

  92. Grumpy says:


  93. FREAK MAN says:

    blur ur eyes its easyer then!

  94. person on earth says:

    i can do it but it makes my brain explode if i do it for too long i like that feeling

  95. why do boys think they are better than girls? because ur jelous. Anyway, Donenit. easy (Dont be sexist. anybody)

  96. me123987645 says:

    i keep messing up on the red (in the color blue). i can read the rest (both color and word) perfectly besides that one.

  97. Debra Savage says:

    Got it first time no problem while I was talking to my cousin in Texas who was going nuts over it. I advised her to walk away and come back it would come to her. She got it as soon after I got it. Great stuff!

  98. Ellie says:

    ….everyone trying to determine whether gender is a major component needs to calm down, because it has nothing to do with it. It all depends on which side of your brain is dominant.

    And really? Some of you need to check your own spelling before trying to call people stupid.

  99. rabbit says:

    I did this in science at school because we had to do a project about eyes/colours and I was the best in the class.

  100. Bruno says:

    This is very interesting to me since english is not my native language, I still get confused but I don’t say the tranlation of the word, instead I say the word that is similar to that in portuguese(exemple: Purple-”Preto” black in portuguese) or I say the word itself in english, even if I’m saying the collor out loud in portuguese. Wierd uh?
