I was playing a sandbox game, trying to learn some different things regarding trade routes, when I got confused by the approval rating color.
100 - 85 % = Green
84 - 70% = Chartreuse

69 - 25% = Grey
24 - 0% = Semi-Random

Ive been shifting around people, to see how they affect happieness.
I get the logic, but it seemed buggy at some moments.

I got the following results:

On one planet

12% = Unhappy
13% = Mutinous
14% = Mutinous
17% = Mutinous
18% = Mutinous / Unhappy
19% = Unhappy


An other thing is that the colors for approval seem in a weird order.
Those are logically colored.
• Estatic
• Happy
• Content

But then Unhappy has a simmilar color to happy.
