Hi,
I don't know what it is, but I just don't. Thing is, I do feel like I need some these days. Starting to look a bit dull and grey, but if I try to inject a bit of colour into my face, regardless of the colour it seems, I look bloody awful!
I would love to be able to go for a bold lip or eye, but I end up looking like I'm playing dress up iyswim. I wear make up every day, but play it very safe with a nude lip and black wing liner. Every. Day
In the evening I'll maybe pop on a gloss, but again, a nudey one and maybe some shimmer on my eyes, with a very very muted pink/purple tone maybe...if I'm feeling wild! 
I've had friends try to take me out my comfort zone and insist I'll rock a red lip for example and then they'll see me try it and are like "oh....yeah, you really can't can you" 
I understand about undertones and have tried all sorts, but nope. Can't even some to do blusher or bronzer.
Is this a thing? Are some people just better to just stay away from colour?
