WebConvert HSV to RGB using spectrum. Convert hue, saturation, and value to RGB. This ‘spectrum’ conversion will be more green & blue than a real ‘rainbow’, and the hue is specified just in the range 0-191. Together, these result in a slightly faster conversion speed, at the expense of color balance. Webfastled has hsv support. you have to use it from the start if you want to "query" it. that's in quotes because you can't ask a pixel what color it is, you can only peek into the memory array that you sent. otherwise you can use a conversion formula for the theoretical equivalent. 1 level 1 · 4 yr. ago tinkerer
