Would it be possible to color code the categories?

This will sound kind of strange, but I have a suggestion for you that would really help me :)

Would it be possible to color code the categories? I have ADHD and to be honest, all the gray is overwhelming to me. The page looks really busy but not in a good way, even though its' simple to use, I have to concentrate to review. I would love to have visual cues where I could glance at the expenses owed and quickly see how much of it would be medical expenses or extracurricular, future or past due, etc. by the color of the lettering.

For example, when an expense becomes past due, the words PAST DUE could turn to red, or show up with a box around them or something to highlight them. "Healthcare and Medical" could be a color. Actually, even better would be the ability to create the categories into whatever color you wanted so each person could individualize it.

Just a thought. Thanks for taking it under consideration.
