You can use the SYSTEM–DIALOG FONT statement to change any font in the font table. However, you can use the SYSTEM–DIALOG COLOR statement to update only those colors that are dynamic. To make a color dynamic, use the COLOR–TABLE system handle. For example:

DEFINE VARIABLE status-ok AS LOGICAL NO-UNDO.
status-ok = COLOR-TABLE:SET-DYNAMIC(n, TRUE).

In this example, n is the color table entry you want to make dynamic. For more information on the COLOR–TABLE handle, see ABL Reference and Accessing the current color and font tables.
