Yes, some colors still look dull in color (mostly the stretch goals), but that is because they are first generation prototypes. If you look at the first videos we made versus the new ones in our update, you can clearly see a huge improvement in the color for certain ones. For example, the color platinum.
At the moment, the colors RED GOLD and PLATINUM are all exceptionally bright and vibrant for both The Nano and The Illumination designs.
The demand for the colors gives me incentive to make it the best it can be. The R&D process can be expensive and time consuming, so knowing there is demand for a color helps a lot. I want to get all the colors to reach the vibrancy of the RED GOLD and PLATINUM.
