My male - Color question

What is the color of my rat. And I don't mean "beige-ish tanish" as a color. I mean the real term for his color. He is being bred to an agouti berkshire and a black berkshire.

He's most likely a fawn. (agouti + pink eye dilute, making the color come out brighter.)

He could also maybe be a champagne/beige, but fawn is most likely.
