The official colors of ΔΤΔ, otherwise known as Delt, are purple, gold, and white . Their flower is a purple iris. I was fairly certain that no self-respecting Delt would want a pillow with flowers on it so I went with a plaid that was purple with touches of gold.
The other side of the pillow has an extremely simplified image of the column from the Westminster College logo. Columns are very significant to Westminster as they are the only remains of Westminster Hall, the original administration building, which burned in a fire in 1909.
