Color Correspondence Between Color and Monochrome PTs
The only colors that a monochrome PT can display are white and black.
The screen data for a color PT can be displayed on a monochrome PT without
alteration and in this case the color correspondences are as follows:
Color on a color PT Color on an NT 21 or
NT31
Color on an NT631
Black, blue, red, or magenta White Black
Green, cyan, yellow, or white Black White (EL lit color)
Likewise, the screen data for a monochrome PT can be displayed on a color PT
without alteration and in this case the color correspondences are as follows:
Color on an NT 21 or
NT31
Color on an NT631 Color on a color PT
White Black Black
Black White (EL lit color) White
Reference: When screen data is created for an NT21 or NT31, black and white are displayed
as white and black respectively at the Support Tool.
When elements are displayed on top of others, normally the background color of
the element on top conceals the element below so that it cannot be seen.
Besides the above eight colors, the color transparent is available for the back-
ground of some display elements.
When transparent is set, nothing appears behind a display element, and the dis-
play element or screen background color underneath it is visible.
