You don't want to make things indistinguishable for the color-blind.

    Like traffic lights, physically separate can be different colors. Red-green colorblindness is most common though, so your easiest bet is to only pick colors where red or green is always zero, then vary the amount the other and blue. If choosing LEDs, most are single-frequency, so ignoring anything orange or lower frequencies removes most of the redundant choices; leaves green, yellow, blue, violet. They're plenty of good websites out there for details.

  That's an important consideration, for sure.
