the colors of the gear will depend on your combination of rear axle gear ratio and rear tire size.

I used this calculator on TCI's website to figure out what combo of gears I needed to make my speedo right when I swapped from 2.73's to 3.55's...

after getting busted for doing 68 in a 50 cuz my speed said I was doing 90.. it was time to fix it.. lol
