It kinda depends what kind of colourblindess you have. I suppose.

ditto. on my colorblind boyfriend. haha. i love it.

i dont have a colorblind boyfriend, but i have a colorblind friend who happens to be a boy.

i can't read it without examining it :P

The circles that say "I love color" may be a different brightness from the other circles. But they look the same to me. However, that's a possible reason as to why he still can see it.

brightness wouldnt matter for someone who is colorblind.

They can only see value, correct?

iunno. my boyfriend has a weird colorblindness..he cant tell the difference between blue and purple. i hear a lot of people who cant see red or green or cant tell the difference between them. i guess theres a big variety.

i see purple as more pink than blue :P

at the end of the day, you learn to call what you all see as green green, even though you see a different colour. the only problems then arise really with naming inbetween shades, so a dark red might look brown, or very light green might look yellow. that's the best i can explain it...

I would actually be tempted to purchase this because of how many colorblind people I know... but then I'd feel like an ass, too.
My father is red-green colorblind, and my best friend is 100% colorblind... oodles of fun.

Brightness and value are basically the same thing. They do look like the same value though.

my friend is colorblind and he can't see shit. it's hilarious!
maybe when it's reprinted i'll buy it for him.
