This is how I got it to work: 1) select the bonny clump 2) from the display menu, select "display material summary" 3) right click the "bonny petal" frame. Select 'edit material' from the context menu. 4)make sure you are in the "color" tab - it usually defaults to this tab. 5) in the 'color production' frame, you'll see two boxes - the first contains a graph, the second a solid color. 6) right click the second box, choose 'edit color map' from the context menu 7) click the 'new keycolor' button and select the color you want. 8) close all of the windows and when you render the petal color should be the color you selected. 'Easy' is a relative term, but this doesn't seem very 'easy' to me -- maybe I'm going about it the hard way, though. Are there any Vue pros out there that know the 'easy' way?
