If you look at the options on Q site, there is often a colour chart showing faces rather than swatches which is quite useful. I know it’s a marmite product, but Laura Geller Balance and Brighten (a brush on powder) does go quite deep as do Tarte and Doll10 which is a liquid. There could be others but it might be worth just having a browse and seeing what illustrations they have. There is also the M. Asam magic finish (also marmite) which comes in deep. I use the neutral one and find it colour adjusts well for me (medium tone, foundation matching is a nightmare for me!) but the one deep might be too dark, it’s hard too tell. They do it in a summer teint which is said to be good for olive tones. Hope that’s of some help! Apologies if not!
