Feature suggestion: Custom HUD color menu, with RGB sliders.

[Shockwave508]

Since there is already a framelimit slider in the graphics config menus, is it possible to add a Custom "preset" for HUD color, which can be adjusted with a trio of RGB sliders, on-screen room permitting? Some players might not be savvy enough to change it through the command console. Brightness safeguards would need to be enforced, to prevent folks from inputting something like [R0, G0, B0] and rendering the entire UI invisible and unusable.
