GuiColorPicker only works in the first canvas created?

I am working on a dialog that opens in a second Canvas window. In this dialog I have a guiColorPicker. However, no matter what I do, the color values it returns are incredibly off. However, if I place this exact same dialog in the initial Canvas, then the color values return properly. Best I can tell, I'm not doing anything differently except doing a .setContent() on one versus the other for the dialog.

Any thoughts on this? Kinda a nasty item... wondering if GUI objects don't follow through at times properly on separate canvas layers, or else I didn't initiate something properly?

Suggestions, comments or thoughts are very appreciated! Thanks!
