March 10, 2003. I have had many many requests for an off-line color conversion tool, like the javascript tools below. See the items marked , below.

• Three on-line Java applets for tristimulus conversions, all with color swatches: 
  • RGB to CIE metrics, with scroll bars and chroma plot.
  • L*a*b* to RGB and other CIE metrics, with scroll bars and chroma plot.
  • Color conversion calculator for many color spaces.
  • Clever Javascript programmers might also be able to use the 'class' files to create their own off-line versions of the above. Click here to download a zipped file containing all three files. Then let me know how they can be implemented off-line, and I'll post the instructions here, OK?
• Off-line color calculators
  • Munsell Color Conversion program
  • Robin Myers' Color Converter
  • Bruce Lindbloom's Calculators

October 22, 2001. Organizations may register themselves, or post an announcement about a coming meeting. If your organization is distinctly color related, and you'd like it to join the distinguished list here at Color Organization Links, go ahead and register, but send me a separate email requesting this.

I have also scoured the site for dead links. I have 380 outside links, and even after 5 hours, still have 30 I can't resolve, but don't want to delete. If YOU have been deleted, or are aware that you link has changed, please contact me to avoid being dropped.

I'm retired. I rarely do an update here. I would just can the whole thing, but once a month or so someone writes to say how great it is, so... I'll keep it going.

December 5, 2000. Special color courses are now being offered at Eastern Michigan University, featuring renowned technologist Bill Longley. 

November 7, 2000. After a 15 month break from any major updates here, and in response to many many requests, I have posted a link to Harold VanAken's delightful downloadable color conversion program:

• Color Conversions to Go! A downloadable color program that shows swateches on-screen, all the usual metrics, PLUS the Munsell trees!

• COLOR NAMING SOFTWARE
  I'd like to see any color metric software put out verbal color names, as in the out-of-print book The ISCC/NBS Universal Language and Dictionary of Color Names. A friend recently reported that one manufacturer has now done this...

• WEB-AWARE SPECTRO'S & SOFTWARE
  Today, color spectrophotometers produce data in the manufacturers' proprietary formats, an instrumental Tower of Babel. Remember that the Internet itself came from a few guys that FORCED government contractors to put FTP (file transfer protocol) on multiple vendors' mainframes.

• I attended the Color & Appearance Div/SPE Conference in Baltimore on 9/16-17/97. Good news: many spectros measure diffuse specular included and excluded in one pass, allowing estimation of gloss along with color. Bad news: each manufacturer persists in using proprietary software rahter than a standard data format, such as ASTM E1708 or JCAMP-DX. So we're not going to have Web-aware spectros' soon.
