I thought that as well, but try this:
LOCAL lowhiteonred
lowhiteonred = "RGB(255,255,255,255,0,0)"
CLEAR
@3,0 SAY "This is bright white on bright red" COLOR (lowhiteonred)
It works in VFP6, probably by virtue of a flaw. Does it work in newer versions?
I wish it didn't as this would help the argument for a re-write of this awful legacy code I'm using.
Thanks
