ClsColor red,green,blue

Parameters

red - red component, 0 to 255

green - green component, 0 to 255

blue - blue component, 0 to 255

Description

Sets the colour Cls clears the screen to.

Fresh after Graphics the cls colour is black (0,0,0). Set it once - say ClsColor 64,128,255 for a sky blue - and every Cls from then on fills with that colour. Handy for flat-colour backdrops so you do not have to draw a background rectangle each frame, or for a quick full-screen flash effect (set, Cls, set back).

The setting is global rather than per buffer, and a new Graphics call resets it to black.
