Ask HN: Dark UI Kit Similar to Webflow, Adobe, Atom?

Hi HN, My latest project features a web-based picture/svg editor and has many buttons. Everything's done except finalizing a UI. I've always liked Adobe's UI elements used in Photoshop, After Effects etc. Buttons are suitably sized, but most importantly readability is excellent preventing straining during long periods. Webflows UI is the closest I've seen to Adobe's and is quite remarkable if I say so. Any recommendations for a CSS based UI kit similar to Adobe's? Thank you.
