#include <SDL3/SDL_pixels.h>

typedef struct SDL_Color
{
    Uint8 r;
    Uint8 g;
    Uint8 b;
    Uint8 a;
} SDL_Color;

The bits of this structure can be directly reinterpreted as an integer-packed color which uses the SDL_PIXELFORMAT_RGBA32 format (SDL_PIXELFORMAT_ABGR8888 on little-endian systems and SDL_PIXELFORMAT_RGBA8888 on big-endian systems).

This struct is available since SDL 3.2.0.
