Set the color of any future shapes to be drawn, can be set by either using R, G, B, A as separate values or by a Color.
The alpha value may not work properly if you're using a material without $vertexalpha.
Due to post processing and gamma correction the color you set with this function may appear differently when rendered. This problem does not occur on materials drawn with surface.DrawTexturedRect.
A Color object/table to read the color from. This is slower than providing four numbers. You could use Color:Unpack to address this. You should also cache your color objects if you wish to use them, for performance reasons.
Example
Draws a 512x512 textured rectangle with the wireframe material.
local myMaterial =Material( "models/wireframe" ) -- Calling Material() every frame is quite expensivehook.Add( "HUDPaint", "example_hook", function()
surface.SetDrawColor( 255, 0, 0 ) -- Set the color to redsurface.SetMaterial( myMaterial ) -- If you use Material, cache it!surface.DrawTexturedRect( 0, 0, 512, 512 )
end )
