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

two: the telekom sued another company because they used "their" color for
ads, but telekom lost in court).

"Linus Torvalds on Patents:
I do not look up any patents on _principle_, because (a) it's a horrible waste
of time and (b) I don't want to know. 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. If somebody sues
you, you change the algorithm or you just hire a hit-man to whack the stupid
git."
