I'm signing this.
I know how to do the Reaver puzzle without a solver, I just can't because to me there are only three colors:
Blue, Red and Yellow
But people tell me there are actually 6.
so, I never lead a Reaver except when guildies are involved and I know someone else can do it.
I see the solution as a UI option named somthing like "Colorbind mode" that can be disabled or enabled (so people not colorblind don't have to see any changes).
The solution can be patterns or just putting some type of text that easily viewable... The reaver puzzle would need to be something that was visually obvious without having to hover your mouse over it.
