As of MasterColorPicker version 1.9 omega / 2.0 alpha, you will now need to download support files from their own packages on this site:
=== JS_toolbucket/SoftMoon-WebWare/Picker.js ===
for <input type='picker' /> support:
=== JS_toolbucket/SoftMoon-WebWare/UniDOM.js ===
for cross-browser and high-powered DOM queries:
=== JS_toolbucket/SoftMoon-WebWare/FormFieldGenie.js ===
To support "MyPalette" and "ColorFilter":
Note that the original UniDOM (version 1) that came packaged with the original MasterColorPicker (version 1) was a rag-tag collection of functions gathered together from other scripts, was incomplete, full of bugs, typos, illogic, and mis-understandings, and therefore resembled something dug out of a kitty-litter box.
UniDOM has been re-written (version 2.0) and is now a respectable package in its own right.
