You also have to realize that the colors you are using may not be that easy to read when you scale down the images you have currently... You may want to consider using different colors...
An example would be #6 (actually all of them
)... Look at SP2 in the last line on the right. It is hard enough to make it out at the size you currently have set... So I would say to continue playing around with colors. A great start though.
You know how many signature revisions I went through?
