My google foo isnt working, but i know this has been discussed in the past, but i cant find it.

I wanted to read the hue out of a pixel (so i could shift it round the colour wheel). I thought it would be trivial, but i’ve over looked something because the results are screwy.

nix, that.

second cup of caffeine brought forth the answer.

I’ll put my ramblings here in case anyone stubles upon this, with the same question.

led[i] stores an RGB value and not HSV.

so i’ll store the hue in a separate array, then i can

hue[i]++

FastLED does have a HSV color space too :slight_smile:

Glad you got it figured out!

@Jarrod_Wagner ​ its probably changed, but i remember led[i] containing RGB and there wasnt/isnt an rgb2hsv conversion.
