Help? Can’t tell if I’m getting grey hair or it’s just the pitch white lighting in the anytime fitness gym

[Liqurt]

Under certain lighting(mainly just in any time fitness my hair is like greyish)

but every other lighting my hair is reddish brown.. wtf? is this grey hair or not? Is my hair greying or normal?

last 2 pics are when it’s normal, first 3 is in the harsh white lighting of anytime fitness
