What color should I dye my hair?

Leave it black but maybe get highlights of another color as well

I like the current colour though 😅

Already Natural black is perfect!

Go with dark auburn!

Purple

You look so beautiful in your natural colour as well 😍

Either a really dark red or really dark purple

Bright Green really stand out

Ombre, maybe a dark purple.

Your natural is dark, glossy and accents and contrasts your coloring very well.
If I you absolutely must color it I would get subtle brown/gold highlights
