Can olive skin be any undertone?

There is a lot of conflicting information about olive skin out there, and I know the definition of it has changed throughout the years. I’m wondering if there are any analysts on here that can chime in about what they’ve seen in their clients, or olive skinned people who have been analyzed. I’m curious what the general trend is… if olive skin generally falls into a certain undertone or if it varies.

I have seen that the international image institute says olive is usually cool-neutral.

Thanks 😊
