There is a function called distant_color in the source, thats where it comes

Count this as an objection. (i) means reopening a fixed bug BTW, don't forget 
that.
I don't think this should be done at all, but lets just consider 24.4:

1) We are talking about a replacing a feature that has no outstanding bugs, and 
has been in place for about 2 months.
2) The only reason too replace it is some personal feelings about "clean 
design", based on unknown principles, that are not documented in any Emacs or 
GNU document.
3) The code for this proposal will be messier.  Distant-foreground is quite 
separate in the code, you can easily find any place where the source handles to 
it.  This proposal suggests modifying foreground, thus changing a lot of places 
where foreground are handeled.  Not only is this bound to introduce bugs, but 
the feature is not as easily seen in the source.

And all this during a feature freeze?  It makes feature freeze kind of 
pointless if any feature can be replaced willy nilly based on a persons design 
feelings.

But this is Stefans call.
