Black isn't necessarily becoming the new beige for GPUs, so therefore it's a colour that should be used more often. UV paint on the PCB would definately be nice however one drawback is the fact that it may worsen the thermal attributes of the 10 layer PCB.
Imho, green is a colour that should be used less now. Instead black, or blue or red. Those three colours are amongst the more popular colours.
I'd also focus on the cooling solution's colour scheme. You may need to be less original but that does not matter. Example: Black SHOULD go with a cooling solution that is not anodized at all. (for Nvidia).
Following the palit colour scheme, it would be very logical to have a blue PCB + Yellow/Goldish/Orange anodized cooling solution. The fan sticker's background should be the same colour as the fan itself with the Palit logo on it. Example, black fan = black sticker. To ensure that the product looks better aesthetically, using a smoother grade of plastic (ABS, etc), would be advised so that the sticker blends in.
This is just a simple solution that wouldnt take much to implement, in addition to the differing PCB colours. It would not cost more to print stickers in different colours, and if it did, not by much.
Going somewhat off topic:
As mentioned just then, think about implementing "product feel" products, and making your GPUs more logically designed. We know that the reference design has flaws, and you guys have corrected that.
Look at the 9800GTX however. The flaw is the fact that the extra power phases makes the PCB so long. How about if we shorten that PCB and change the size of the fan and make the whole casing of it similar to the 9800GX2? BUT! Instead of a smooth gloss cover thats a potential fingerprint magnet, a matte casing!
Same can be said for the HD3870X2. Sure the PCB design is efficient. However cooling is something that lets it down a bit. You guys could could design a cooler which would cost roghly the same but completely trample the reference design in efficieny...
Example: Linked copper flower cooler with two fans. Due to the heatpipes connecting all the cores the PCB does not bend as much. Memory banks lined up in a better manner and also cooled with the memory plates.
