Don't forget, the lights behind the cluster could very well be white, but they show red because the gauge cluster is translucent red. In this case, you would need to change the gauge cluster itself to be translucent whatever-color-you-want without needing to change the lights.
I hear you on the too much red though. My thought is to change the needle to a different color.
If anyone figures out a way to add some contrast to the gauge cluster PLEASE PLEASE PLEASE let us know! Just when I think I am getting used to ALL that red- I look down and think "Look at all this red!"
Even if the hash marks on the speedometer had some white- it would be so much better. It looks great during the day (I have the non sport package) But man- all that red!
maybe mazda will see that the dash needs some contrast (the first year models are always guinea pigs); and will make some changes for the 04 or 05+ models. in that case, we should be able to swap clusters then
