Look into colour analysis and draping. You can do virtual or in person draping. Virtual - you take a photo of your face in a natural light, without makeup, covering your hair with white fabric. You cut out your face and place it on different colour backgrounds. Cool and warm. Your face should stand out before the background colour. If it looks like you’re under the colour, or you’re blurry, that’s not your colour. If you look healthier, jaw lifted and you’re the first thing you notice when you look at the combination, it is your colour. If it’s a warm background then you’re warm. If it’s a cool background then you’re cool.

Similar with in person. You try on different colours of clothes. Do it in natural light, no makeup hair covered. You put on different coloured fabric right under your face. If you look washed out, it’s not your colour. If you look healthy, it is.

Washed out doesn’t mean pale. It means you look tired, grey, or yellow with bags under eyes etc. Your eyes are drawn to the colours instead of you and they drain you. Healthy doesn’t mean tan. It means your skin is glowy and even, you see it first, bags are not as prominent, it can have a rosy tint or light yellow tint but it wouldn’t be sickly like in the case of being washed out.

The veins are not reliable at all. Draping is the best way to establish.

This seeks very subtle, I sometimes feel like I’ve put a lot on, but it’s neutral and blends with me, and people say that ’ I look great without makeup’… and I’m just thinking shit, I must look really ugly truly without it if this much effort equals no makeup for you.

It might be that it’s just so natural and well blended. If you want it to definitely show, maybe use a bit more and different colour scheme/harsher lines?
