I have med/fair golden skin tone. Hazel eyes with muted blue-green base, gold and rust around iris with ‘freckles’. My natural hair color is a pretty neutral light/ medium brown and my grays are a very white silver.
Should I stop wearing many of the shades I used to look good in? I don’t want to look washed out or frumpy. Thank you for your help!
There is no earthly reason why you should not continue to enjoy your Autumn colors with grey hair. As long as you are still feeling good in them! It's not just your hair that makes up your color palette your eyes and skin are very important too and are likely to maintain your contrast.
The transition period and adjusting can be a difficult time. If you feel that the colors begin to overwhelm you, take a little more care with your makeup and perhaps wear a brighter lipstick to maintain the brightness.
Wear your prettiest and most flattering colors close to your face rather than neutrals to warm up your complexion.
As your hair appears to be adopting a silvery tone it's very likely that your contrast will increase again and you regain more brightness.
