And I too agree and will do it that way on the real thing. The model would have required taping off and painting an item twice - I was too lazy for this effort.
Czechman, thank you for charitably referring to re-doing the photoshop - again, too lazy - that is simply the model sitting on a box top in front of my computer screen with an Art Deco building picture in full view mode.
The area behind the upper grill, and in front of the hood side should be the lighter color. Change that and redo the photoshop and you may like the results better.
I agree... that panel is part of a surface that should not be broken up with different colors.
IMHO, of course.
