Question about mob drops relative to level difference

Sewagerat - Lost City

As the title states...

Does anybody know the percentages to which the drop rates change when, for example the mob turns light green or is blood red? I know that these change but not to which extent.

Would a 3 lv difference (light green mob) mean 25% less drops or blah blah blah

Any help? Maybe GMs?

I believe up to 2 levels is fine, then a small drop at 3-5 and so on.
