Is hair colour subjective data or objective data?

I need help with my psychology homework, I believe its qualitative data but I'm not sure if objective or subject.

My friends are stuck on the question too.

I think subjective because everyone can see someones hair colour as a different shade of the colour so technically we won't all see brown hair as the same exact shade. Also my hair is brownish blond, so 50% of people would call it brown and the other 50% would call it blonde...

So is hair colour subjective.

My friend argues that it is objective because everyone will see the hair colour as only one colour but I don't know.. I could be overthinking this... Please help
