Purple Theme - Green should not represent incorrect placement

[joshistoast]

I've had coworkers accidentally enable the purple theme, where the color purple represents correct placement of a letter and green represents incorrect placement of a letter. This caused them to get very confused and continue placing letters incorrectly... because they're highlighted green.
It would be best if the misplaced letters were changed to a light purple, or another color that would suggest the color theme is different.
