Checking the internet I noticed that there is no color picker to be used with the FASTLED library. This library was created to handle strips of neopixels, but FastLED defaults to using a richer 'rainbow' color map, instead of the traditional 'spectrum' color mapping.
when you choose a color in the hsv format it does not match the color displayed on the led, due to the different color scheme. Perhaps some option in this fantastic color picker that can be chosen between the 2 color schemes would be ideal. More info about rainbow color map here.
thanks
sorry for my english
