Very useful utility (and toy) for anyone working with color on a computer.

Features include:

Fantastic (no kidding) Color Wheel;
Zoomies (pure color window blocks you can generate to test colors over wide screen areas, and which you can "doodle" with using powerful positioning commands);
RGB/HSL scrollbar adjustments with "Color Guides" that greatly facilitate their use, RGB scrollbar controls can be locked in tandem for easy tint/shade generation;
2-color blender bar;
total 6 color encodings:
HTML #, RGB decimal, RGB hex, Hue-Sat-Lum, decimal programmer's (like VB), hexidecimal programmer's (like Delphi);
also BODY tag and CSS code generator;
screen "pickup" tool having three types of "pickup", two of which allow you to grab colors from crude (dithered) bitmaps(!);
a web-safe color enforcer;
both a webpage and a "shapes" playground used to fine tune color contrasts (Working Color can be sync'd to any playground item so it can be fine-tune adjusted "in situ");
fullscreen web preview screen with font family selection and HTML file creation;
color palettes with many features, including default web-safe and pure Hues palettes, user-definable palettes with save and reload, quick-links to user-defined palettes, floating palettes with save and reload of floating palette sets, powerful means of generating color ranges on palettes;
