I think it's better in this way:

Very easy: Cyan

Easy: Teal

Somewhat easy: Blue

Medium: Green

Somewhat hard: Yellow

Hard: Orange

Very hard: Red

Extremely hard (reserved): Brown/Maroon

Insanely hard: Black

In this way it will cause less confusion and I think yellow-orange-red-black colors are a group, so I think it is better to use it for hard difficulties only.
