Great simple table of the 4 main color groups = my experience is you can successfully wear all of the warm colors whether labeled warm/light warm or spring/autumn.same for cool/light cool or summer/winter. Reminder: I'm in the cool color palette.
For a simple look - Large white tiles - Kerry Phelan Design. Similar layout of our small bathroom with a floating sink! Would prefer a glossier finish to the tiles since we won't be tiling all the walls "wet room.
