It's more keycap that I'm concerned about. That transparent set I linked are Out of Stock, I'm not sure which of the keyboards on retail have the character on the keycap transparent. I want the backlight to see the symbol in the dark, not to look cool.
Ah, sorry, misread your post. The K10 caps do (K10 pro don't), if you scroll right to the bottom here there's a pic and a vid showing the legends lit, in addition to the vid RedFlames posted. Plus any shine through cherry compatible keycaps will work on that board if you end up wanting a replacement set. Just be careful they math the board ISO / ANSI layout. The ones on mine, on the pic I posted earlier in the thread, are Taihao Deep Forest Blue for the same reason. LED's are set to white, so all the legends are lit in the dark. Bar colour, the ones on the K10 should look similar.
Worth noting that the transparent keycap set you linked to earlier might not have been any use to if that's what you're after as the keycap itself is transparent but the legends aren't - this is what they look like when lit up:
Corsair K55 RGB PRO XT will do until I get to really work out what I want and can actually find it in stock. Will revisit in a year or so.
