This is an "inky" color palette, very neutral, bland colors.
I like to use this color palette for line art or minimalist drawings. It helps to emphasize shadows and other thick line work.
I think this would look nice if you pick a couple colors or few colors as your palette, perhaps over a white background.

I hope you find creative inspiration from it.
