Create a palette structure with the specified number of color entries.


SDL_Palette* SDL_AllocPalette(int ncolors);

Function Parameters

ncolors represents the number of color entries in the color palette

Return Value

Returns a new SDL_Palette structure on success or NULL on failure (e.g. if there wasn't enough memory); call SDL_GetError() for more information.


The palette entries are initialized to white.


This function is available since SDL 2.0.0.


SDL_Palette* palette = nullptr;



// Create new palette with 4 colors

palette = SDL_AllocPalette(4);

if (palette == nullptr) printf( "Error: %s\n", SDL_GetError() );


// Set green and blue of the first color in the palette to 0

palette->colors[0].g = 0;
palette->colors[0].b = 0;

// Set render draw color to red

SDL_SetRenderDrawColor(renderer, palette->colors[0].r, palette->colors[0].g, palette->colors.b, palette->colors[0].a);


palette = nullptr;
