I heard a lecture from a patent lawyer this semester and we only touched the topic "color" for a couple of minutes (the lecture was more about traditional trademarks, patents etc). What I remember though is that it is very very hard to defend a color in court. For example the German Telekom tried to defend "its" color "magenta" but lost (at least afaik) in court [1,2] (it is probably interesting to read the comment [3] too). On the other hand I am quite sure that some RGB value difference won't help at all (the difference between (x,y,z) and (x+1,y,z) is surely not perceivable) and defining a good measure for the "distance" of two colors is far from being trivial. Probably they do some kind of survey (seems they did it in [4] where they asked the addressed "community" ("angesprochene Verkehrskreise") to find out if they link a color combination with some company or not.) My personal summary: use any color you like. I don't think there is any chance to get sued for this, and if they really do it, it will hurt them by far more than the KDE project. KDE probably infringing so many software patents that some stupid color trademark law will not add much to this anyway. All IMHO of course. best regards, Marco (disclaimer: I am neither a lawyer nor an expert in trademark law) (sorry, but both all links are in German language only. Summary for the first two: the telekom sued another company because they used "their" color for ads, but telekom lost in court).

The fact is, technical people are better off not looking at patents. If you don't know what they cover and where they are, you won't be knowingly infringing on them.
