Improving Greedy Bankers for Colour Blind Players - Help Needed!

Hi everyone. One of the issues that came up at Eurogamer Expo that I really wanted to fix was the fact that the game was very difficult for colour blind players. This is something I really wanted to fix, because I don't want to lock anyone out of playing the game over something that's easy to fix.

For example, here's a screenshot from the four-colour version of the game...



... and the same screenshot as viewed by someone with red-green protanopia (as far as I know, the most common form of colour blindness). I used the Vischeck web tool to simulate the view (which seems to have stopped working today, unfortunately).



The problem is fairly obvious! The easiest, and hopefully most effective way to do this, was to add symbols to the gems to make them easier to distinguish. These can be toggled on and off by the player. My question is, for any colour blind gamers out there, does this make any difference? Is there anything I can do to improve the effect?

Here's the game board without symbols...



... and here it is with symbols...



Any pointers and words of advice?

  1. Some stuff about the colour-blindness mode in Upbot Goes Up here: http://ishisoft.com/archives/288

    Apparently they tweaked the colours as well as adding icons, though I'm not sure how those colours were chosen.

  2. For UpBot I just experimented with colours and kept running them through the filters here ( http://www.ryobi-sol.co.jp/visolve/en/tryonweb.html ) until they seemed distinctive enough.

    I also did a colour-blind mode for my Clockwiser remake ( http://ishisoft.com/archives/117 - fourth screenshot). As well as altering colours I generally simplified the graphics and increased contrast.
