Are there color pickers for Emacs?I use the excellent rainbow-mode to highlight colors in CSS files. However, this assumes I know what color I want. Are there any color pickers that I can use for CSS editing inside Emacs? Ideally, I'd really like something where I can make colors slightly darker/brighter/redder/greener, like the Firefox color picker: Alternatively, I've noticed customize-face offers a color picker from a set of 54
