How to change color of beveled shape with linear fill?

[Contours]

When I create a simple shape with a linear fill using a single color and then apply a simple outward bevel, I lose the ability to change the "base" fill color.


It seems to occur after I've applied a rounded bevel. The bevel portion appears to become a separate element with its own colors.

Is there a way to Select All and change the base color with a single click? (but not White, which clears the linear fill)

Thanks in advance for any suggestions.
