S Color correspondence between NT631C and NT631
The only colors that an NT631 can display are white and black.
The screen data for an NT631C can be displayed on an NT631 without alteration
and in this case the color correspondences are as follows.
Colors at NT631C
Black, blue, red, magenta
Green, cyan, yellow, white
When screen data is created for an NT631, black and white are displayed as white
and black respectively at the Support Tool. On the display of a monochrome per-
sonal computer, the display at the NT631 matches the colors displayed at the Sup-
port Tool, but when a personal computer with a color display is used, the colors are
reversed.
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.
