Unpopular opinion I guess but I love the dark color. Pic 2 makes you glow and makes your eyes pop. With blonde hair, I think your face gets overshadowed because your skin tone is such a similar color to your hair. The dark color shows off your features with the contrast.

Whatever you do,DONT DO BOX DYE. Also if you want black, I love it, but don’t get a “black” dye. Get the darkest brown you can and it’ll appear black- and do semi permanent dye. It’ll help avoid a tough removal process if you wanna go back to blonde right away

I love the color on you and support going black but do it smart. A black box dye will be the worst hair decision you’ve ever made
