SDL_SetTextureColorMod
Use this function to set an additional color value multiplied into render copy operations.
Contents
Syntax
int SDL_SetTextureColorMod(SDL_Texture* texture,
Uint8 r,
Uint8 g,
Uint8 b)
Function Parameters
texture |
the texture to update |
r |
the red color value multiplied into copy operations |
g |
the green color value multiplied into copy operations |
b |
the blue color value multiplied into copy operations |
Return Value
Returns 0 on success or a negative error code on failure; call SDL_GetError() for more information.
Code Examples

Remarks
When this texture is rendered, during the copy operation each source color channel is modulated by the appropriate color value according to the following formula:
srcC = srcC * (color / 255)
Color modulation is not always supported by the renderer; it will return -1 if color modulation is not supported.
You can call SDL_GetRendererInfo() to fill in an SDL_RendererInfo structure with the information about the current renderer. This structure will have SDL_TEXTUREMODULATE_COLOR set in the mod_modes mask if color modulation is supported.
