Field properties (as listed and documented in the HyperTalk Beginners
Guide) include frameColor and textColor. FrameColor cannot be changed
using a script.
TextColor can be changed to one of the sixteen current colors in the
colorSet. Here is the script:
set the textColor of card field field1 to n
where n is a number from 1 to 16. The highlight color is always black; the
text within the highlight becomes the compliment of the textColor.
Note: Be careful about being misled by the actions of the "color" section
of the "field info" dialog where the highlight color is the same as the
textColor and the text within the highlight becomes white.
