Well you can jump on to the Mod Top registry and have a look at some different colors on their. You will be able to get some color Mod Top material from Laysons, It is not exact but perfect for what you want to acheive, will look real cool too. Post pics when you have done it.
I have problem with Mod Top registry - the pictures don't work for last month or so. Do you experience the same, or is problem on my side?
