Nattyware / Pixie: I just saw this on TechTV a couple of minutes ago, and it fills a need I’ve had for a long time. When I’m trying to decipher a color, I’ve been known to crank open FrontPage just to use its color picker.
“Pixie is an easy-to-use, fast and tiny utility designed especially to fit the needs of Webmasters and Designers. Its a colour picker that includes a mouse tracker. Run it, simply point to a colour and it will tell you the hex, RGB, HTML, CMYK and HSV values of that colour.”
It’s free, and only 8KB, though it manages to soak up 2 MB of RAM if you leave it sitting in the system tray.
