yes, I know that one, but I already now some users are colorblind, but I want to test adjacant fields with different background colors and see what still works.
I can quickly make one, just thought I would be re-inventing a wheel here.
As a color blind developer (Primarily red green), I find that putting two fields next to each other with either different shades of red or green as the highlight or red in one and green in the other frequently results in all of them looking like they have the same highlight.
As my wife would say I'm color challenged. So a couple of things that might help you.
Don't use different shades of red or green.
Use either a red or a green, not both.
Attached is the Apple color chart from FileMaker's color selection. As I look at it:
Black : No problem
Blue: No problem
Brown, Red,Green, Orange look similar. Without the labels I probably couldn't name them.
Magenta, Cyan are very similar
Yellow and Green are close as well. I find that when I'm skiing, there are coats and pants that are either a very bright yellow or Green. My Wife says green, I say yellow. If could put a Yellow and a Green next to each other they would look the same to me.
The catch is that color blindness like this varies a good deal between people. It comes down to the number of active receptors in the eye. It tends to be a primarily a male issue. Women can be color blind, but when they are the world is really gray scale.

You can contact me directly at RichardSRussell@tds.net, and I'll e-mail you a file I've developed with a bunch of color swatches in it, to make it relatively easy to pick out the ones you want to compare.
Thanks all for the feedback, I will post my experiences.
I promised results on these tests.
These may vary on a person-by-person basis as there are degress of color blindness, so on the horizontal axis of the standard color palettes it may be hard to see differences, but on the vertical axis (intensity within the same color column) the difference becomes clearer.
So e.g. if you have green and red adjacent fields, make sure you also make a jump in the vertical axis.
When the green is 3rd field from the bottom, the adjacent red should be either 2nd or 4th from the bottom.
This nuance will be picked up in most cases.
