let me preface this with...i've never organized by closet by color, but I did on Sunday night! i had some antsy energy and it was let loose on my closet. i was a sneezy mess afterwards, but it was worth it. i relentlessly purged (no comment if you see something that should have been purged) & learned I have the majority in these colors: white, black, & gray. You need to know all this..
