How can you have a different cycle color and trail color in Armagetron

First, press the Tilda key (~).
the three commands to change colors are:
(Case sensitive)
color_r_1 (whatever number you want)
color_g_1 (whatever number you want)
color_b_1 (whatever number you want)

If one of the three numbers you choose is 16 or higher, the trail and the bike should be different colors.
