Returns the blue component of the current drawing colour, 0 to 255. The current colour is whatever the last Color set - or, after GetColor, the colour picked up from the screen. Together with ColorRed() and ColorGreen() it lets you read back GetColor's result, or save and restore the drawing colour around a routine that changes it. See also: ColorRed, ColorGreen, Color, GetColor. |
