How should I choose colour for a bonus link? Is there any common way mappers generally use? There's so many bonuses and I am a bit uncomfortable choosing one for each of them.

Generally speaking each bonus is given a different shade of the color of the superbonus it is in (if your map has those), or a shade of the color you choose as the color for your bonuses.

Examply:
General color: blue

Bonus 1: light blue
Bonus 2: blue
Bonus 3: dark blue
Bonus 4: navy blue
Bonus 5: baby blue
etc
