Sorry I thought you were talking about the normal curve (inner) of standard keys. I'm not looking for adventure and I'm not sure id be excited about dome or exterior curvature in keys.
Are there some pretty solid sites for custom key sets? Im looking for some tone. Figured id give it a shot. instead of one uniform color.
My bad. Here are the ever popular candidates.
1.
mechanicalkeyboards.com
There are virtually billions of keyboards and keysets on this site and although I don't fancy most of them, surely everyone will find something that they like.
For colour, you are looking at Vortex PBT and Ducky PBT sets. Vortex sells plenty of doubleshot PBT in your standard OEM profile, and they are nice thick PBT too. Ducky has nice colours, but you must be careful as they have these funky legend printing methods including "engraved legends", which are literally carved physically into the keycap without any ink.
Lots more. Tai-hao sells nice ABS and PBT, but
beware of Tai-hao PBT as it has a coating called Anti-Biosis on the outside of each key, which attracts grime and gets sticky. You can remove it with isopropyl alcohol like I did, but it takes a whole damn day with a toothbrush and a bowl of ISA, and is very tiring. Tai-hao ABS never comes with the coating.

wasdkeyboards
WASD now sells "doubleshot PBT" sets which, at $40 are arguably the stars of the show. They are actually made by Vortex (virtually the same you see on MK.com).
The "custom" sets are problematic because no one knows how the legends are printed. They could be lasered, which is subpar compared to dyesubs. Also there are reports that they have a UV coating that wears off an makes the keys look extremely ugly. But if you want 100% custom colors there are no other options.
3. zealpc
Zealpc makes the custom "Zealio" switches, but they also sell keysets from time to time. They sell what I think is the only POM set around. I have not tried POM but apparently this Cherry POM set is an original from Cherry Corp. and is fantastic while different from both ABS and PBT.
4. Originative
You will find some very expensive SA and GMK sets on Originative. GMK sets are manufactured in Germany and are in Cherry profile, which is shorter than regular OEM profile. They are ABS and doubleshot and I don't understand the hype and price, but some people swear that they are the ultimate in quality keycaps.
The "Dolch" that you find here is made by GMK and is I guess considered closer to the "original" Dolch, while the Tai-Hao "Dolch" is considered by some to be a cheapo clone.
5. Clueboard
Skully's site is mainly for Clueboards, but he also sells Modern Selectric because he designed it. Earlier last year the group buy for Nantucket Selectric finished, and later after all of the orders have shipped he may have extras for Nantucket on his store as well.
This ain't an exhaustive list; I'm sure there are plenty of sites out there that I've missed. In the US there are
tons of options.
EDIT
@Solaris17 the Tai-Hao dolch is a nice place to start, if the coffee brown scheme is for you. It is quite cheap if you can find it. I'm not sure if MK.com stocks it. Otherwise, the Ducky and Vortex sets are quite nice but I have not owned them like I have the Tai-Hao Dolch.
