make the Yellow panels shading colors the same as the panel too
'Fraid you lost me there.
When you do a bevel effect, two colors are used for the shading that gives the inset look (black and white by default). Now, instead of black and white, use the panel's color, it will look a lot better.
Actually, there isnt a bevel on it at all. The way i did it was to keep it looking GI-like. Allow me to explain.
There is a down panel and an up panel, right?
The Up panel gets a Black outer-glow on Multiply and a White Inner-glow on Overlay.
The Down Panel gets a white Outer-Glow on overlay (smaller than the up panel) and a Black Inner-Glow on Multiply.
The Multiply is for the diffused GI shadow, the overlays is a semi-highlight and semi wear-and-tear. A white overlay on the gold creates a brighter and lighter yellow so in essence i already did that, lol. I don't know if the render I uploaded reflected that, though.
