Decal background color changes when placed on model

[mdristy]

I have a jpeg file with blue lettering and a perfectly white background. When I use it to create a decal in Creo 2.0 (in Appearance Gallery) and I place the decal on my model (which is white), the decal background color comes out gray. I want it to be white and match the white color of the model. Interestingly, when I "Render" the model using the "Render Window" tool in Creo the decal background color then turns white. How can I get the decal's background color to be white in the normal Creo shaded view?
