The Concord University colors are maroon and gray.  A song printed in the 1927 Pine Tree Yearbook mentioned the colors:

Old Concord is the Place for Me

Old Concord is the place for me, place for me, place for me;
Her life is full of jollity, jollity;
Just as we love the golden rule,
So do we love our dear old school.

Her profs. They are the proper stuff, proper stuff,
They give us lessons long and tough, long and tough,
And yet they’re loved by every one
Who is a loyal Concord son.

We’re for our dear Maroon and Gray;
We win new victories every day,
To always do our very best,
Is the motto for our C.S.C. (Concord State College, now Concord University.)
