Most keyboards have RGB led soldered on the PCB. Then the switch has a transparent body so that the light can be seen.
If you want to change the switches there are probably 2 versions - hot-swap and soldered to the PCB. If you are not handy with the soldering iron then I would recommend to look for hot-swap version.
I have a Ducky Shine 7 keyboard with Cherry Red and I must say so far so good. I just had to replace a spring at the spacebar for something a little stronger one (from Cherry Black). I sometimes rest my thumb on the spacebar and that pressed it too easily.
If you look at the Cherry MX switches you will see a lot of options (pressing force, tactile response, pressing stroke). It can be difficult to choose.
The red switches are really easy to press (probably easier than the keys on my HP laptop). On the other hand they do not give a feedback when they are pressed so for someone that can lead to the double-press problem you mentioned if you press them only half-way. I do not mind since I press them all the way to the bottom. With blue switches I do not expect you will see that problem at all.
