subtractFromRGB()

FASTLED_FORCE_INLINE CRGB & CRGB::subtractFromRGB

(

fl::u8

d

)

Subtract a constant from each channel, saturating at 0x00.

Note

This is NOT an operator+= overload because the compiler can't usefully decide when it's being passed a 32-bit constant (e.g. CRGB::Red) and an 8-bit one (CRGB::Blue)
