Converting colour names: Hex & RGB colour values...

Thanks Chip, this (I think) works for the mouseColor (which seems to always
return RGB triplets), but if you have a button which has the background
colour set to "red" - then (unfortunately) the backgroundcolor of that
button is "red" - not "255,0,0"

Baseconvert does not like "red"... so how do you force a function to return
an RGB triplet? Or better still given MC can understand RGB, HTML/Hex and
"red" - how do you convert between them without writing your own lookup
table for all those MC colour names?
