GL.Color

static function Color (c : Color) : void

Description

Sets current vertex color.

In OpenGL this matches glColor4f(c.r,c.g,c.b,c.a); on other graphics APIs the same functionality is emulated.

In order for per-vertex colors to work reliably across different hardware, you have to use a shader that binds in the color channel. See BindChannels documentation.

This function can only be called between GL.Begin and GL.End functions.
