I would prefer that manufacturers use the traffic light colour scheme:
* Red: stopped or off (preferably dimmed of completely off)
* Yellow/Amber: startup or error state in which the device needs intervention
* Blue/Green: running properly
- NL807 3y ago>Blue/Green: running properly this would be redundant as you'd know that the device is running in most cases
- voakbasda 3y agoFor battery powered devices, red should be “charging”.
- coryrc 3y agoYou don't want to make things indistinguishable for the color-blind.
- hnaccount_rng 3y agoWhat would be an appropriate set of color choices then?
- baq 3y agoConstant, blinking slow, blinking fast, Morse code blinking
- coryrc 3y agoLike 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.
- cf100clunk 3y agoThat's an important consideration, for sure.
