No, not at all. I think Barnett copied Colorado because his son liked their black uniforms.

"Gary Barnett brought back the black in a big way in 1992, switching the team's jerseys to black for the first time ever. Of course, his reasons had nothing to do with NU's history. He had come from Colorado, and his young son had suggested that Barnett try black and purple uniforms. The players loved them, and so the look stuck for a decade."
