color of oak leaves

I have 2 very large common (brown leaved at this time of year) oaks in my yard , and a newly springing up (very bright red leaved ) baby oak. I wanted to know if this is just because the sapling is so young and it is just another common oak,that will turn green leaved in the summer and brown leaved in the fall,  or is it possible that this is a different variety of oak that will be red-leaved even as an adult? I guess my real question is do the leaves start out a different color when the tree is very young and darken with age? Thank you.
