Hammer partially changing color

[accidental_reefer]

Hello, I have a hammer with two branches. On one branch, the two heads have maintained its color but heads on the other branch have lost color. What is this signaling with respect to lighting?

I use AI Prime. I do not have par readings. Disregard frag on the left in second photo.

Thank you.

Really can't tell a difference with the pic being so blue. Do you have an orange filter so we can see the difference?
