Is there a simple way to randomize color of text and background of a field
without getting a combination which is unreadable?
A simple way I can think of is making a list of readable combination and then have the random function chose one:
get random (<number of lines of fld fCombinations>)
set textcolor of fld <field> to item 1 of line it of fld combinations.
set backgroundcolor of fld <field> to item 2 of line it of fld combinations
If you don't want to name the color by names, and use the 3 digits sets then you need to change the item separator, of course.
To make your combination list, maybe you could begin with a simple color list (not more than a dozen of color), and have a script randomizing text and bg separately among the words in this list, displaying an ANSWER "refuse" or "keep" and adding to the combination list if not refused. This way you could either eliminate the combination if it is unreadable (or really to uggly!) or keep it in the definitive combination list.
But, is this psychedelic fantasy worth so much time and work? ;-)
I had a similar problem with fonts, styles and sizes: they had to be readable and fit in the display box.
