Yes I color code my closet. I can't help it. It's just prettier that way.
When I am shopping I tend to gravitate towards the color coded displays too. My eyes just like the matchy - matchy.
Painting is that way too. When I paint something for a specific room, I take special considerations with the color and the surroundings where the piece will be displayed. Why not make it work with the room?
Artists have debated the "match art to your couch" battle for ions. Some say that it lessens the work if created to match a sofa. I say, color code the crap out of it. Why not?
I think my closet masterpiece would agree.
