Use colour to differentiate output from input

Suggestion for enhancement: use color to differentiate output from input

Indented input and left-aligned output was a good idea in the time of printing teletypes (https://youtu.be/_DTpQ4Kk2wA) but it looks a bit awkward by today’s standards.

In addition to indentation, consider differentiating between input and output with color and/or font.

It may be that all we need is an option to preserve syntax colouring for old input, just like the Windows IDE can:

Note that APL2 and APLX can differentiate between various types of input and output, e.g.

@abrudz this would be great. In fact, blue for input, black for output, and red for errors is just perfect. I would also use gray for boxes and train trees.
