This logo clever uses negative space to blend the year they're celebrating with their brand colors. They start with a vertical rectangle that holds a staggered number 90 that goes edge to edge. The white number leaves spaces for three colors in the top, middle, and bottom of the rectangle with the word "years" at the top and the name of the university at the bottom.
