Function SetupRandomPalette

examples/NoisePlusPalette/NoisePlusPalette.h:325–336

This function generates a random palette that's a gradient between four different colors. The first is a dim hue, the second is a bright hue, the third is a bright pastel, and the last is another bright hue. This gives some visual bright/dark variation which is more interesting than just a gradient of different hues.

// another bright hue.  This gives some visual bright/dark variation
// which is more interesting than just a gradient of different hues.
void SetupRandomPalette()
{
  // Create a new palette with 4 random colors that blend together
  currentPalette = CRGBPalette16( 
                      CHSV( random8(), 255, 32),    // Random dim hue (low value)
                      CHSV( random8(), 255, 255),   // Random bright hue (full saturation & value)
                      CHSV( random8(), 128, 255),   // Random pastel (medium saturation, full value)
                      CHSV( random8(), 255, 255));  // Another random bright hue
  
  // The CRGBPalette16 constructor automatically creates a 16-color gradient
  // between these four colors, evenly distributed
}


// This function sets up a palette of black and white stripes,
