###### (This is the legacy documentation for SDL2, the previous stable version; [SDL3](https://wiki.libsdl.org/SDL3/) is the current stable version.) # SDL_SetRenderDrawColor Set the color used for drawing operations (Rect, Line and Clear). ## Header File Defined in [SDL_render.h](https://github.com/libsdl-org/SDL/blob/SDL2/include/SDL_render.h) ## Syntax ```c int SDL_SetRenderDrawColor(SDL_Renderer * renderer, Uint8 r, Uint8 g, Uint8 b, Uint8 a); ``` ## Function Parameters | | | | | ------------------------------ | ------------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | [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 (int) Returns 0 on success or a negative error code 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)(). ## Version This function is available since SDL 2.0.0. ## See Also - [SDL_GetRenderDrawColor](SDL_GetRenderDrawColor) - [SDL_RenderClear](SDL_RenderClear) - [SDL_RenderDrawLine](SDL_RenderDrawLine) - [SDL_RenderDrawLines](SDL_RenderDrawLines) - [SDL_RenderDrawPoint](SDL_RenderDrawPoint) - [SDL_RenderDrawPoints](SDL_RenderDrawPoints) - [SDL_RenderDrawRect](SDL_RenderDrawRect) - [SDL_RenderDrawRects](SDL_RenderDrawRects) - [SDL_RenderFillRect](SDL_RenderFillRect) - [SDL_RenderFillRects](SDL_RenderFillRects) ---- [CategoryAPI](CategoryAPI), [CategoryAPIFunction](CategoryAPIFunction), [CategoryRender](CategoryRender)
