I donāt really get your color choices. I wonder if itās kind of random. It doesnāt seem like itās trying to match what the pedal does, in some abstract way. Nor the leds.
For the most part we just pick swatches that both of us like. The bare metal was kind of an experiment. We like a matte finish because it tends not to smudge as easily as gloss. For Sparks and Ghosts, āblack controlsā and āwhite controlsā are part of the UI, so for those it has to be a color that black and white text cuts against. Beyond that though there isnāt too much rhyme or reason and we just like to try new colors.
