I used to use TheDraw for doing ANSI art, but I also ended up making my own ANSI drawing tool back then. It's stupid to think of now, but one reason I made it was because I had a monochrome monitor, so I couldn't "see" color. I wanted a feature where I could put the cursor over a character and it would tell me the color there when I was drawing so I could still use color in the work.
I wasn't prolific, but did do a handful of ANSI art pieces for local BBS SysOps who liked them well enough. Only later on I realized when I got an actual color monitor that I had a few color mistakes in them and they never told me. lol

I recommend Moebius for traditional ASCII and ANSI art.
