I had my epiphany!
Ok, I'll put some pics of the apartment right before I moved in, so careful to your eyes, it's awfully pink:
That's the librairy: left and back walls will be Tar Brown, right wall beige, middle section beige too.
Now living room:
Left and back wall stem green, right wall beige, middle section beige.
And, to fit in the beautiful purple, I'll paint the lower half of the corridor Summer Plum! Ta-da!! This should be interesting!
Warning: epiphanies in the CatWorld are always subjected to change.
