I prefer colored all the way, specially when "boilerplate" words become less vibrant, like 'def, fun, function, begin, end'.

Pure white/black words are really painful because it causes paralysis when trying to re-read a different page or file from the current one.

I simply get stuck trying to decide what to read first, because everything looks the very same, specially outside the peak minutes of the medication.

About Copilot, for instance I found really easy to give more instructions or context, or restart with new instructions whenever it spills bullshit code, even on programming languages that are unusual for me.

The problem is when to really give up because I still believe that I can convince the bot to spill what I really need. If I'm not familiar to the problem, even knowing that the bot is spilling bullshit, I feel a analysis paralysis deciding if I will handle manually, step by step, like the "old days", or giving more context to the bot.

So becoming familiar to certain classes of problems is something helpful, instead of specific implementations in certain languages.
