PPT Questions
What does this sentence mean? The user of the system and the sub-sections of the system they visit are all PPTs. Please define what "system" is, what visit is and what PPTs (Power Points?). Should we use a table that has a column for example? --Dan 18:11, 13 July 2006 (UTC)

PPT stands for Party, Place or Thing. It's not clear from the article what the rest means. Take a look at some of the discussion at featuredrivendevelopment.com or nebulon.com for more information about color modelling and the Archetypal Domain Shape (aka the Domain Neutral Component), such as this discussion. -- Hugh, 19 October 2006

What was meant by this is that the green items are the nouns of the system. The objects and the direct objects in gramatical terms. They are the -things- that have actions done to them, or the actors who perform the actions. So in your book collection, the books you own would be PPTs, while the time period during which you owned them would be moment intervals tying you, the original shop (PPT) where you purchased the book, and whoever (PPT) you 'loaned' or sold the book to which caused it to disappear from your collection.

Pink or Purple?
The main text of the article mentions Pink as the color for moment-interval, yet the example diagram uses purple? The UML template UML uses purple too, so which is it? --Dex1337 01:51, 26 October 2007 (UTC)

It was supposed to be pink. If you read below the colors, you'll see that they mention that the colors were originally based on the pastel PostIt note palette. The colors depicted are far from pastel. Around 2003, when I learned Color Modeling, 3M took a foray into other color combinations, and the pastel sets became hard to find. If memory serves, the vibrant color pack was close to the colors depicted. That may explain the discrepancy between the text and the colors. Jdmarshall (talk) 22:41, 5 March 2008 (UTC)

Err, by that I mean: Color modeling seems to work best on a white board, so sticky notes are virtually de rigeur. Anyone who learned or taught Color Modeling would use colors that were available as sticky notes of some kind. And after 2003 and perhaps as late as 2007 (not sure when the pastels came back), one might make do with the yellow-bright blue-purple-neon green packs, and would tend to display that color scheme, for purely practical reasons.

UML Required?
Not sure about the title of this page. While UML is probably the most natural way currently to represent object models built using Peter Coad's color-coded class archetypes, the technique does not mandate UML. The technique was first used with Peter Coad's own notation in 1997. We switched to UML on that project in 1998 and it was included in the title of Coad et al's book on the subject in 1999. 'Object Modeling in Color' would probably be a better title with UML described as currently the most approporiate graphical notation for it.--86.142.8.96 (talk) 10:21, 20 October 2009 (UTC)


 * I agree with changing the title of this page, for the reason given above plus the tacit implication (although untrue) that the UML standard incorporates this particular color scheme, which it does not.Jlhollin (talk) 16:49, 1 August 2014 (UTC)
