I am colorblind, not sure for which colours…

Normal chart: 3&7 look the same
5&9 look the same, and 11 is close
10&12 look close

Colour blind chart: 4&6 look the same
7&9 look the same, and 3 is close
10&11 are close

Can you setup a colour wheel and let user select colours for each player? A game called LUX allows user to do this. http://sillysoft.net/

5/9 and 10/12 are all you need to change from the normal graph.
6/11 can be told apart but are pretty similar.

The color blind version has much worse colors for me

I’m red-green colorblind.

Normal vision chart:
3&4 are pretty close, enough to make it hard to tell apart
9&11 look identical

The “color-blind” chart is definitely worse for me:
4&6 look identical,
so does 7&9
so does 8&11

Chart 2:

2 & 5 look very similar -red (especially if I turn down the brightness)

3, 4 & 6 look alike (looks like purple)

7 & 9 look alike (light blue or purple?)

(or 7, 8 & 9 if the brightness is turned down)

10 & 11 (look like shades of gray)

Hope this helps.

I posted this on your blog but I’ll repost here as well:

I am red/green color blind (in addition to others) but here are the ones I cannot tell the difference between (or great difficulty trying to tell)

1st chart:

2 and 3 on your chart I can tell the difference between due to the different intensities (darker red, lighter green) but if the intensities were the same, I wouldn’t.

5 & 9 look very similar (almost the same)

same with 6 & 11

and 10 & 12,

Also if the brightness is turned down on my monitor 5, 9 & 11 ALL look the same as well as 3, 4, 7, 10 & 12… (ALL look like the same color)

Is this helping or only making things more complicated

What *may* help is giving each team/group a distinct intensity/brightness from each other, (a light blue vs a dark red or a dark, dark green versus a bright yellow)

I’ll post chart 2 in the next comment.

I’m not color blind, but I suggest you try a little utility called Color Oracle, it is very useful for building accesible applications.

I agree that the color blind chart is worse. On the color blind list 7 & 9 and 4 & 6 are nearly the same to me. Also 5 & 10 are close. If they weren’t near each other in the chart I probably wouldn’t be able to tell them appart.

On the normal list I have issues with 9 & 11, 1 & 6, and 3 & 4 are a little too similar

I am partially color blind. Here are the colors I have a problem telling apart: On the Normal vision chart I can’t tell the difference between 1 and 6, 3 and 4, 9 and 11. On the color blind chart is almost worse. can’t tell between 1&3, 4&6, 7&9.

Hope that helps!

I think it’s nice of you to make your game fun for color-blind people. I’m not color-blind, but I am legally blind (not blind, but visually impaired) and there are some iPhone games I just can’t play because I have a hard time seeing them.

For example, the numbers on the planets are hard for me to see, so I largely ignore them, although I generally play higher than level 4 now.

I am also hearing impaired, and I’ve only ran into one game that had some sounds that were hard to hear. For the most part, though, most games do pretty well since the iPhone’s default headphones are pretty loud at full volume.
