Digital
For my digital art, I use Clip Studio Paint V5 with a Tabmate remote controller that replaces most keystrokes with programmable buttons.
In the early days (2015-2023) I used Inkscape vector graphics editor to color scanned images of ink drawings. With CSP, I draw and color using a Wacom tablet. I strongly encourage both fine artists and graphic artists to try Clip Studio Paint by clicking the link below.
