There are superior visual representations of math as soon as you add specificity such that you can measure the difference between representations in terms of their impact or other property. Equation coloring according to semantics stands out as an example of this. Interestingly, this example already has wider adoption in code than it does in math. As someone who has tried to format a latex paper to have coloring and has not had to do the same for colored code, I can understand why. Yet if you look at KhanAcademy as an example, the technology lifts much of the burden from doing the coloring, so they do the coloring, because it helps to highlight the key ideas.
It can be a fun exercise and illuminating to go over equations you've written down and try to translate them to colored variants. The classification task forces your mind to more deeply engage with the equation and can improve understanding.
