So far it seems like E should be Violet and F should start the spectrum again At Red. If you don’t care, don’t post. If you don’t think it matters, you’re right! Read and comment on something else. Lol thanks Any other input is appreciated But........ I’ve been dying to associate the right Colour with the right Notes. I want to take one guitar and one bass.... sticker each fret with the notes and colour of the note.... Every source I’ve researched has a different opinion... spectrum of light waves do roughly correspond with the frequencies of sound waves .... I’m hoping some of you have thought about this as well or are interested enough to do some searching... I think you could also shade those colours up and down per octave. I’d like enough reasoning to definitively decide on the right colours for the right notes. There’s info all over the world....I found technical information associated with numbers and spirtual information associated with the senses. What do you think? I’d like to do this with a higher end fretlight guitar. Lights in the fretboard light up to show chords but more importantly all the relevant notes in any scale you can think of. Would be an amazing upgrade for the fretlight concept to have the notes coloured.
