Here's an interesting story of a girl in Michigan with Grapheme-Color Synesthesia. In other words, she visualizes each digit, zero through nine, as a different color.

For her, and others with the same condition, it adds a new splash to math work.
For centuries, we humans have been building big bridges. And just when we thought we had the science and math figured out to span waterways most efficiently, we may be in for some new discoveries.
Matthew Gilbert, a structural engineer in the United Kingdom, with his team of researchers, has developed a numerical optimization program that could help us build large suspension bridges even more effectively. Read more from Science.
"It should be evident that each step in my career has rested on a firm foundation in mathematics. For me, the study of mathematics was the key that opened the doors to the universe."
