Thanks, Roman.
For a quick solution: I noticed that if you click "compose color" in the "Properties" dialogue for cnv, it gives the RGB values, so I can just plug those into the converter subpatch in cnv's help patch.

So the bit mask for those values is the following:
((rrrrrrggggggbbbbbb)*-1)-1
whereas the 'color' message to the iemgui objects expects a 8 bit/channel number, which has this bitmask:
((rrrrrrrrggggggggbbbbbbbb)*-1)-1
So if you want to read the color values from a .pd file and send them to the iemguis, you need to bitshift the channel parts from the 18bit scheme to make it fit into the 24 bit scheme.

Hello, Can anyone tell me how to figure
out what value to send a [cnv] object
to get it to display the colors shown in this
patch? If I try to take one
of those big negative values from the pd file I get a
totally different
color.
Thanks, Jonathan
