We Domers are very particular about our school colors. Our Papal Gold comes in shades of old gold, mustard, vivid yellow, goldenrod, and that one hideous shade found on the 2009 The Shirt. Our Madonna Blue, on the other hand, has remained fairly steadfast over time. Let's not even venture into the realm of our alternate greens, which nearly set the Internet ablaze when Adidas proudly rolled out the eye-gougingly-bad Zubaz Shamrock Shake uniforms a few years back. (It's no coincidence that our Under Armour deal was struck shortly thereafter.)
However, the Irish have stated loud and clear that they can't stand Carolina powder blue or Duke blue on the same court as them.
