Color Chooser for Graph Chart

Hi,

I've successfully used Lebans/Kreft's ColorChooser API for controlling
colors of textboxes, command buttons, etc., but when I try to use it
for controlling the lines on a Microsoft Graph Chart (MSGraph.Chart.8)
line graph, only certain colors actually display correctly. Looking
at the Graph Chart object, it looks like only 56 colors are available
to the Data Series collection. My question is is there anyway to
modify the ColorChooser API to open a common dialog box that only
displays the 56 colors available to the Graph Chart, as opposed to
opening the common dialog with all 256?

Thanks!
