So I wasn't going to publish this, but there was a thread about someone wanting a color picker tailored to programmers and I happened to be developing one for myself and a web developer friend.
The main feature is the string at the bottom: you can type in any formatting with the modifiers, and via a rollover 'copy' button you can copy the string to your clipboard with the active color information. It's got a swatch library, alpha, and it even saves your swatches when you close the sketch (as long as you use escape!).
The code may be a bit wonky, as I am self-taught and this was a Sunday Afternoon Project, if you know what I mean. I'm not a good enough programmer to turn this into a Tool just yet, but that's certainly a long term goal. If anyone wants to collaborate to make that happen I would gladly take the opportunity to learn.
Happy to share- please let me know if you make any improvements!
