Match to futuristic/space Traveller ooh. this would be a super fun project. color-match spectrum of a favorite photo. even more so if the spectrum was also collaged from photos, not just color matched on illustrator.
color scheme for apartment bathroom? This one is probably my favorite palette, excluding that dark brown (if I used that it would be sparingly). Sand, greys and lighter blues for main rooms, dark blue for bedroom, grey for master bath.
