“I had this architectural training that I got from [graphic designer and friend] Saul Bass, starting in the ‘80s. My father was an aeronautical engineer, and my grandfather was a patent person. I had that whole background. I don’t make three-dimensional things very often. I’m usually working on two-dimensional work. This was the first time I was able to really make a physical object with that training. The yellow and red in the sign are fast colors. I found a kind of very light blue, like a gray. So rather than using gray, which is so flat and dead, I put a little bit of color into it, making it this light turquoise, to set off the vibrancy of the primary colors.”
