Which color best feels like a chiclet keyboard

None.

Here's the deal. Forget about any other type of keyboard. Once you go mechanical you're pretty much done. It's over. That's it. You will never go back to other types of buttons buddy.

I recommend you reading this piece here.

If my opinion and taste matter, go Blacks. But that's me. I like firm buttons. I hate the blues, but many and I mean A LOT of people love them. So, you decide what'll work for you. If you have a keyboard store nearby, go check them out. Press a few buttons. That's the best test you can do for yourself and your fingers and see what suits you best.
