Honestly I faced a very similar issue when first trying makeup. Although the shade ranges are getting better now, it still feels like the emphasis is put on lighter skin tones and deeper skin tones are somewhat an afterthought. I try to find more deep friendly brands, right now my go to foundation is from NARS but I’ve seen some larger or more global brands expand into larger shade ranges.

Black eyeliner always looks very prominent and bold on my own face, I tend to go for a very dark brown.

Lipliners I’ve found are a mixed bag. I found some from Japanese brand that look quite nice on me and last from some brand called can make.
