ray_catI used an actual camera (Fuji XT3) shot in raw and didn't do much to the photo so that is a pretty accurate rendering. In my opinion it looks like a pretty deep purple with maybe a bit more blue than the photo showed. I would say in person it is deeper blue more than bright purple - maybe I should have lowered the temperature a bit. I am really happy with the keycaps.
mattyTeeeeI have a very similar setup (gmmk pro, Holy pandas, susuwatari mt3 caps) and its very good for the price. The sound is nice (don't bother with polycarbonate plate it sounds much cheaper than the aluminum). The only downside is no flex. But the way I type I don't even notice that. I did also replace the stabs with durock V2s which is a must if you're already spending hundreds of dollars. An alternative option is the keychron q1... Much more bouncy but also sounds more hollow. However with that one you may be able to find the right amount of bounce-hollowness tradeoff, whereas the gmmk pro will always sound hefty, but have no bounce.
