Detailed Description

Minimal RGB color struct.

This is a lightweight replacement for FastLED's CRGB struct, implementing only the features used by SensESP's LED blinker system.

Member Function Documentation

operator-()

constexpr CRGB sensesp::CRGB::operator- ( const CRGB &  rhs ) const

inlineconstexprnoexcept

Binary subtraction operator with saturation.

Subtracts each channel component-wise, saturating at 0. Used for color inversion: CRGB(255,255,255) - color

Here is the call graph for this function:

operator=()

CRGB & sensesp::CRGB::operator= ( const CRGB &  rhs )

defaultnoexcept

Assignment operator.
