You can create any color palette you wish; a couple of starters are provided: These palettes are all declared as PROGMEM, meaning that they won't take up SRAM on AVR chips until used. Am I right to conclude that one cannot exactly fill a strip with a palette due to incIndex having to be an integer? Hi everyone, I am new to using Fast LED - I am looking to produce a static gradient from one color to the other, no movement is necessary - just the gradient needs to display when powered on I attempted to explore using the Palette Knife tool, and have also reviewed the “ColorPalette” example sketch that comes with the FastLED library, and where I Palette transitioning (use your own palette variables though) EVERY_N_MILLIS; What is NOT included: * FastLED. FastLED : ColorPalette. There are a bunch of mode options to choose from within the sketch, including adjusting the speed and steps of the preset palettes and creating your own palettes and modes. Here’s a video of the example code running; the entire code for this example is about 150 lines, and takes up just 6. h: Utility functions for color fill, palettes, blending, and more controller. Just wanted to share a sketch I made that incorporates a button with Color Palettes (modified from Amelia Tetterton's FastLED Palette Button) and in this case the Fire sketch by Hans Luijten. 42 // generator, and the combination is extremely powerful. h Saved searches Use saved searches to filter your results more quickly Useful for blending palettes. For example, if the colormask if CRGB(200, 100, 50), then the pixels' red will be faded to 200/256ths, their green to 100/256ths, and their blue to 50/256ths. In the case of writing into a CRGB array, the gradient is computed in HSV space, and then HSV values are converted to RGB as they're written into the CRGB array.
