We are using Visio 2010 to create technical diagrams that need quite a few separate colors, more than are possible in the themes. We don't need themes (shadows etc), just colors. I defined a color palette in a VST template file and thought I could apply those colors as needed, only to find I couldn't find a way to apply the colors in the palette:

• The palette colors are not shown in the color selection for Fill, Line, Shadow, or Font.
• If I open the palette and click on a color, it does not become the current color anywhere that I can see.
• If I select a shape and click a color on the palette, it does nothing.

Can someone explain how the colors in the palette are applied to the figure being edited?

I have never tried to do this. However, here is a link that "may" shed some light on the topic. If not, you may want to go into their forum and ask the same question....it is strictly a Visio forum.

Notice that the exchange following that post ends inconclusively. I think the poster was describing the same problem I have but worded it differently, and it was left unresolved.
