Rainbow condition

[Estellios]

Seriously, it states plainly White > Yellow > Red > Rainbow for progressively worse success rates and has been that way since launch. Doing a TON of crafting for hamlet defense turn ins, this is also the order for lowest to greatest quality gains upon success. It's entirely obvious even from eyeballing it. The notion that the riskier colors would not have any kind of payoff is extremely stupid even for this game.

The light may also turn from yellow, to red, to multiple colors flashing rapidly. Though these states represent progressively lower chances of success when executing commands

There is literally no other way to interpret this statement other than White > Yellow > Red > Rainbow for best to worst success rates.
