The source code has plenty of comments that describe the various LED effects, but for the sake of completeness, I’ll explain them here too:
- Off mode, where all LEDs are off. This is the default.
- Rainbow mode, where all keys are the same color, and they cycle through the rainbow colors.
- Rainbow wave mode, where a rainbow marches across the keyboard keys.
- Chase, where a blue pixel chases a red one across the board and back. It is a neverending chase, blue never catches red.
- A bunch of static colors: red, orange, yellow, green, blue, indigo, and violet.
- Breathe, which slowly pulses all of the LEDs.
- AlphaSquare, probably the first “off” mode you found: whenever you press a key, it lights up LEDs that show the letter or number you typed. It is a 4x3 font, so some of the symbols are a bit hard to recognise. But it is a fun one!
- Stalker will light up the key you press, and fade it away slowly. If you type fast, it leaves a trail of fire, kind of.
Then we wrap over, and start over with the off mode.
