The colors refer to the types of Cherry MX switches and the common clones have mostly stuck to the format. Reds are really light and linear (no bump when you press down), Brown is light with a small tactile bump, blue is light and clicky. No beige, but clear is heavy with a big tactile bump, and green is heavy and clicky. You can get keyboards with non-Cherry branded switches really cheap these days. I’ve seen some on amazon for $20 (not that these would be great quality)
