| [SDL_Renderer](SDL_Renderer) * | **renderer** | the rendering context.                                                                                                                                       |
| float                          | **r**        | the red value used to draw on the rendering target.                                                                                                          |
| float                          | **g**        | the green value used to draw on the rendering target.                                                                                                        |

| float                          | **a**        | the alpha value used to draw on the rendering target. 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.
