 * glow color is like: 1 or 0 for R G and B channels

 * colors are blended with additive color mixing:
 * 1 1 1 = white
 * 1 1 0 = yellow
 * 1 0.5 0 = red with a smaller aura of yellow, not orange
 * 0 0 0 = transparent
 *
 * -n is for inverting channels and making the mixing substractive
 * resulting in C M Y channels
 * 1 1 1 = black
 *
 * there is a total of 7 light colors and 7 dark colors + intensity
