OK, I have a little bit more time and net here now. When I defined the colours 
15 or so years ago I was asking the community for feedback, but I think most 
people didn‘t even quite understand the purpose yet, so there weren‘t really 
any changes to it.

I defined the colours based on three things, the Windows 95 colour palette, the 
WMAN window structures and the colours needed to successfully port QPAC2 to 
them. Only one or two additions were made for other software like QD (which 
still has the editor colours in its own config block as I felt these were not 
generic enough in usage). 

With QPAC2 it was necessary to have a foreground colour and one other font 
colour, for which I created the name „middle ground“. This was part joke and 
part lack of a better name. Plus, nobody complained ;)

I never realized this could be interpreted as STRIP colour, especially as I 
actually defined one „STRIP“ colour, too: „Title text background“. I don‘t have 
my laptop with me, but I don‘t think there is the concept of a „STRIP“ colour 
in the data structures, so I probably never really considered it. Sorry for the 

I was hoping that some day there would be a style guide, but adoption of the 
system palette was slow and finally I forgot about it. Still, many applications 
these days use them, so I consider them a success nonetheless.

One more thing: they are defined somewhat conservatively because if you give 
too many options thing get even more messy. I know Per was always on the rather 
bleeding edge of WMAN UI development so probably struggled a lot more with them 
than anybody who simply duplicated the QJump style.

Cheers, Marcel
