What about the questions on the razer keycaps? I understand there is some overlap but this is more focused on the keycaps. I apologize if I'm being redundant.
One of my biggest questions is about the stabilizers. The cap on the left side - that won't work with a keyboard that doesn't use mx stabilizers. Of all of the keycaps I've looked at I've never seen any mention of the stabilizers in the description / purchase information. How do I know if they'll be set up for costar (which is what I'm planning on getting)

MX stabilisers come in two flavours - Cherry (where the stabiliser bar is underneath the plate and you have an MX switch in the middle and two MX switch-like things either side. The keycap (e.g. as you have shown) sits equally on the switch and both other bits.
Costar stabilisers have the stabiliser bar above the plate, and a small separate plastic insert that you manually place in the hole on either side under the keycap, and then hook the stabiliser wire over one and then the other, before finally pushing the centre socket down on the switch.
Keycaps that fit one will fit the other.
MX keycap is MX keycap. They will fit all MX keyboard assuming the sizes are available. If you know you will be replacing keycaps right off, then you want to avoid keyboards that use odd sizes of keycap. Certain keyboards are very hard or impossible to get complete coverage on in aftermarket keycap set or sourcing from vintage. You will have the easiest time and best selection if you choose keyboard that has 1.25 ctrl, alt, win, menu and 6.25 spacebar. Especially avoid keyboard that have other size spacebar than 6.25 or 7 like CM TK, Corsair, Noppoo Choc mini, iOne (Razer, Max, Tessoro, CM Pro, etc.) as they are not offered at all.
You can use regular keycap on backlight keyboard. Personally I think it looks nicer...

like that with Cherry doubleshot.
How would that look like if two colors next to each other were different? Would the colors start to blend together?
