helps.

on mouseDown
  put the mouseColor into thecolor

  set the numberFormat to "##"

  put formathex(baseConvert(item 1 of thecolor,10,16)) into R
  put formathex(baseConvert(item 2 of thecolor,10,16)) into G
  put formathex(baseConvert(item 3 of thecolor,10,16)) into B


  put thecolor into cd fld "rgb" of cd "stageLg" of stack "HemTools"
  put "#" & R & G & B into cd fld "hex" of cd "stageLg" of stack "HemTools"

There are three ways of specifying a colour: name, rgb, and htm hexcolour...

How do I convert between them? I was about to write a routing to convert rgb
to html colour values, and I couldn't get around the problem of the colour
functions returning colour names instead of rgb triplets - anyway I am sure
there must be a built in technique?
