Functions
CHSV	ColorFromPalette (const CHSVPalette16 &pal, uint8_t index, uint8_t brightness=255, TBlendType blendType=LINEARBLEND)
	Get a color from a palette.
CHSV	ColorFromPalette (const CHSVPalette256 &pal, uint8_t index, uint8_t brightness=255, TBlendType blendType=NOBLEND)
	Get a color from a palette.
CHSV	ColorFromPalette (const CHSVPalette32 &pal, uint8_t index, uint8_t brightness=255, TBlendType blendType=LINEARBLEND)
	Get a color from a palette.
CRGB	ColorFromPalette (const CRGBPalette16 &pal, uint8_t index, uint8_t brightness=255, TBlendType blendType=LINEARBLEND)
	Get a color from a palette.
CRGB	ColorFromPalette (const CRGBPalette256 &pal, uint8_t index, uint8_t brightness=255, TBlendType blendType=NOBLEND)
	Get a color from a palette.
CRGB	ColorFromPalette (const CRGBPalette32 &pal, uint8_t index, uint8_t brightness=255, TBlendType blendType=LINEARBLEND)
	Get a color from a palette.
CRGB	ColorFromPalette (const TProgmemRGBPalette16 &pal, uint8_t index, uint8_t brightness=255, TBlendType blendType=LINEARBLEND)
	Get a color from a palette.
CRGB	ColorFromPalette (const TProgmemRGBPalette32 &pal, uint8_t index, uint8_t brightness=255, TBlendType blendType=LINEARBLEND)
	Get a color from a palette.
CRGB	ColorFromPaletteExtended (const CRGBPalette16 &pal, uint16_t index, uint8_t brightness, TBlendType blendType)
	Same as ColorFromPalette, but with uint16_t index to give greater precision.
CRGB	ColorFromPaletteExtended (const CRGBPalette256 &pal, uint16_t index, uint8_t brightness, TBlendType blendType)
CRGB	ColorFromPaletteExtended (const CRGBPalette32 &pal, uint16_t index, uint8_t brightness, TBlendType blendType)
	Same as ColorFromPalette, but higher precision.
template<typename PALETTE>
void	fill_palette (CRGB *L, uint16_t N, uint8_t startIndex, uint8_t incIndex, const PALETTE &pal, uint8_t brightness=255, TBlendType blendType=LINEARBLEND)
	Fill a range of LEDs with a sequence of entries from a palette.
template<typename PALETTE>
void	fill_palette_circular (CRGB *L, uint16_t N, uint8_t startIndex, const PALETTE &pal, uint8_t brightness=255, TBlendType blendType=LINEARBLEND, bool reversed=false)
	Fill a range of LEDs with a sequence of entries from a palette, so that the entire palette smoothly covers the range of LEDs.
template<typename PALETTE>
void	map_data_into_colors_through_palette (uint8_t *dataArray, uint16_t dataCount, CRGB *targetColorArray, const PALETTE &pal, uint8_t brightness=255, uint8_t opacity=255, TBlendType blendType=LINEARBLEND)
	Maps an array of palette color indexes into an array of LED colors.
void	nblendPaletteTowardPalette (CRGBPalette16 &currentPalette, CRGBPalette16 &targetPalette, uint8_t maxChanges=24)
	Alter one palette by making it slightly more like a "target palette".
