How were the colors of the book covers selected?
The distinctive red color of the books represents three institutions. Red is the company color of Eli Lilly and Company, where Dr. Boyd was located when the book series began. Indiana University’s colors are cream (white) and crimson (red). Purdue University’s colors are gold and black. Adopting one color from each its historical academic parents, the colors of Indiana University – Purdue University Indianapolis are red and gold. This explains the significance of the red, white, black, and gold colors. The bright cover of RCC has led to it being referred to as “le livre rouge” in France.
