I have seen the color of that Blonde D' Aquitaine bull called everything from dark cream to light red to real straw colored.
Note the muscle pattern, small testicles, and color along with the sign in the background mark him as a British Blonde D'Aquitaine bull. If you want to see a similar color in a Charolais look at this bull: http://www.wellscharolaisranch.com/herd-sires.html
