Character color setting system

Abstract

Abstract PURPOSE:To prevent the foreground and background of characters from being displayed in the same color owing to misoperation, etc., by comparing a specified color with current foreground or background colors and stopping a specified color setting procedure when the colors are equal. CONSTITUTION:An application program 421 starts the background color setting procedure and foreground color setting procedure in an operating system 422 prior to character display operation, and the contents of a current background color storage area 424 and the contents of a current foreground color storage area 423 are set. A color number is passed and the procedure is actuated so as to update the contents of the current background storage area 424. Further, when the specification of the passed color number is not correct as a color number or equal to the contents of the current foreground color storage area 423, error information is set. Consequently, characters are prevented from being invisible because the background color and foreground color are set to the same color.
