API Frame SetBackdropColor

s provide two methods to apply tint to their : frame:SetBackdropColor(red, green, blue[, alpha]) frame:SetBackdropBorderColor(red, green, blue[, alpha])

• SetBackdropColor tints the background component of a frame's backdrop
• SetBackdropBorderColor tints the border component of a frame's backdrop

• red : Number - Proportion of the original red colour to remain, from 0 to 1
• green : Number - Proportion of the original green colour to remain, from 0 to 1
• blue : Number - Proportion of the original blue colour to remain, from 0 to 1
• alpha : Number - Proportion of the original opaqueness to remain, from 0 to 1

• These values only modify the existing colour and alpha of the backdrop files; it its not possible to be lighter or more opaque than the original
• Subsequent calls to the same function will override previous ones; i.e. they apply to the original texture directly rather than interacting with the previously-tinted one
