Am I overreacting about this?

I was on the phone with my boyfriend today and I told him about my plans to dye my hair again. I told him I’m going back to black hair. He then he says “you should go platinum blonde” which wasn’t what I expected to hear. I was hoping he’d say something like “oh that’s gonna look nice” etc. I’m his first Latina gf and his ex’s are all white, blonde haired women. I immediately felt some type of way but I didn’t say anything. Now I’m in my head wondering if I’m even his type? All his ex’s look the same and im the complete opposite. Am I overreacting and getting in my head for no reason?
