Suggestion from colorblind guy

I appreciate the color code feature and all, but frankly it's a lot of work to read a map - you can't just glance and see what's what.
So I have two suggestions to help with this:
1) we colorblind folks have a better shot at discerning colors if there's a bigger swatch to look at - the colored numbers in use today just aren't a big enough patch to identify at a glance. I'd prefer to see a black or white number on a colored background (circle, etc).
2) Use some higher-contrast colors. Why mess with purple and green when black and white are available? Black/White/Gray/Red/Yellow/Blue solve a lot of problems. But you still have the other 2 players in 8-player games, which brings me to:
3) Combine colors with shapes - put a number on top of a green circle, black square, blue diamond, etc. Problem solved.
