colortables and colr2 directory

Today I had some problems with colortables.

My current mapset from grass startup is mapset1
I run d.colors on a raster cell map that is in mapset2.
Then is seems that the valid colormap for this cell map ends
up in "mapset1/colr2/mapset2/cellmap".

I spent over one hour looking for this changed colortable before I found it.
Could someone explain this mystery with the the colr2 directory and if
this is documented somewhere. What is the idea with the colr2 directory.
