Prism 239 Application & MDEF
© 1991, 1992  Dean A. Snyder

Prism 239 application demonstrates a custom menu I created for quick, easy, and informed color selection on the Mac.

It displays, in a meaningful hexagonal arrangement, the standard 256 System colors, minus the 18 darkest colors (for aesthetic reasons), but including the hilite color, if any.  White is shown in two places, hence the "239" designation.

Press the Option key, or drag across the eye dropper, to toggle desktop color selection on and off.  When on, you can select a color from anywhere on the desktop, not just from the menu. You can use Prism 239 in this mode to get the red, green, and blue color values for any pixel on any of your screens — particularly useful if you are color blind like me and can't tell purple from blue!

If you are running System 7, press the Command key to select a gradient of the current color.

Prism 239 application is freeware and may be freely copied and distributed, but must not be altered in any way.  It may not be sold for profit. It is not public domain software; I retain the copyright.

Prism 239 MDEF, the menu definition procedure code which calculates, displays, and manages the Prism 239 color selection menu, is a commercial product and programmers can license it from me.

There is a one-time licensing fee of $20 in U.S.A. currency to a single, independent developer for unlimited use in all projects. Multiple-developer firms pay $20 in U.S.A. currency for each different commercially released product using Prism 239 MDEF. I accept U.S.A. checks, cash, money orders, or C.O.D. orders (in the continental U.S.). Add $10 shipping and handling fee for each order shipped.

In general, at this point in time, I cannot provide technical support for the Prism 239 MDEF, other than the documentation provided to licensees.

Although I have programmed Prism 239 application and Prism 239 MDEF in all good faith, neither I nor anyone else will be held liable for real or alleged damages associated with it. The Prism 239 MDEF is sold as is.

I have tested Prism 239 on a Mac II, Mac II si, and Mac Quadra 900 (with cache on).

Much thanks goes to Robert A. Mintzer, Chicago Macintosh guru, for the many selfless hours spent helping me learn Macintosh programming, and, in particular, for several great suggestions regarding Prism 239 itself.

Also to Dave Schulz and Geordie Korper at University Computers, Chicago, for indulging my penchant for repeated testing on their various Macintoshes.
