Why use RGB or hex instead of base-10 for colors?

Question

RGB uses base-255, hexadecimal uses base-16, and colors like "Red" in an IDE are translated to base-2 binary. Why not just use base-10 (zero to nine) to represent colors?

i.e. the base-10 number 99999 is the same as navy blue.

I made a code to show you can easily convert base-10 to base-255 or base-16.
