Colors is a standalone JavaScript library that comes with features to manipulate colors in multiple ways.

The library can handle multiple types of unit conversions including RGB to a Hexadecimal and Hexadecimal to RGB or HSV.

It can get the complimentary color of any Hexadecimal or RGB value and can generate random color values.

P.S. The library is still under heavy development and in beta phase.

Designers, who wonder the RGB of any color that is around their mouse can get the results instantly.

Small utility named Pixie, runs on your system tray, you can call it with a click and it will show you HEX, RGB, CMYK & HSV values of any pixel you’re pointing.

Many designers take a screen capture, run their favorite image editing software like Photoshop, Fireworks and paste the capture to the image editing software to get the image color values. With Pixie, no need for these steps.

An extra feature of Pixie is, it shows the x y position of the mouse pointer.
