Maybe you knew this about me and maybe you didnt (and it isnt technically about me, anyway) but my dad is a mathematician. When I was really little, I remember he had one of those triangles you use to draw straight lines and measure angles and whatever else it is you do with triangles... and it was this beautiful, translucent, glowy shade of orangey pink, like nothing else Id ever seen. He may have had a protractor in the same set. Maybe he still as them. I dont know. And its probably because I was so little that the association I developed is so strong even now, but that neon pinky-orange color, like the color of hottest lava--bright, sunset-y, and enigmatic (exactly what color is it, truly?)--is the color of Mathematics, in my mind. Does that make any sense?
