Add shothand for using color escapes when printing to the terminal

[boxbeam]

We could have a color function that emits a color code sequence for a color by name, so you could use it like "This is {color("red")}some colored text{color("reset")}"

Hello. I'm the one who was presenting in the other room today, and the one who asked about this functionality.

In case its helpful, I've found this to be a great guide to how terminal graphics work - it's decades of hacks upon hacks that somehow work, but are often complex.

@Redempt That can make it simple, but does not give as much control as entering color codes directly - in Python, if I wanted to print that red text, I'd use "\x1b[31msome colored text\x1b[m" (1b is the hex code for the escape character). Obviously less readable, but as someone who does a lot with color control escape sequences, I often need to be more precise than simply specifying "red" or "green".

That's a great resource, thank you!

I think that simply adding '\e' as an escape character that maps to \u{1b} is enough for my use case - I can get by with \u001B as well - it just took a bit of experimentation to figure out the right syntax for that.
