Screen Background Color
The background color of the entire screen can be designated with the “Back-
ground” screen attribute. Screen attributes are properties set for each screen with
the Support Tool.
Text Display Color
The color of characters (character color) and that of their rectangular frames
(background color) can be specified.

Background color
Character color
Graphics Display Color
The colors of lines and tiling patterns can be specified for graphics.
The colors that can be designated for tiling patterns are the color of the pattern
itself, the background color of the pattern, and the color of the outline of the tiled
area.

Line color
Reference: When a lamp, a touch switch, and a graphic are displayed in color, part of the
frames of the display elements may be invisible because of the combination of the
background, outline, and tiling colors. This is a phenomenon peculiar to a color
LCD, not a failure of the system. In such a case, change the color combination.
