WebJun 22, 2015 · The FastLED HSV-to-RGB conversion has a built-in gamma correction of 2.0, which means that the Value scale is not linear. Instead it is adjusted to be closer to visually linear, or to put it another way, it comes out darker.. If you want, you can just perform the brightness effect adjustments in RGB space, or alternatively pre-adjust your …

http://fastled.io/docs/3.1/group___pixeltypes.html 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. mercury room kcmo
