| [SDL_Renderer](SDL_Renderer) * | **renderer** | the rendering context.                                                                                                                                                                                             |
| Uint8                          | **r**        | the red value used to draw on the rendering target.                                                                                                                                                                |
| Uint8                          | **g**        | the green value used to draw on the rendering target.                                                                                                                                                              |
| Uint8                          | **b**        | the blue value used to draw on the rendering target.                                                                                                                                                               |
| Uint8                          | **a**        | the alpha value used to draw on the rendering target; usually [`SDL_ALPHA_OPAQUE`](SDL_ALPHA_OPAQUE) (255). Use [SDL_SetRenderDrawBlendMode](SDL_SetRenderDrawBlendMode) to specify how the alpha channel is used. |

## Return Value

(bool) Returns true on success or false on failure; call
[SDL_GetError](SDL_GetError)() for more information.

## Remarks

Set the color for drawing or filling rectangles, lines, and points, and for
[SDL_RenderClear](SDL_RenderClear)().

## Thread Safety

You may only call this function from the main thread.

## Version

This function is available since SDL 3.1.3.
