Color scheme for master. Monochrome combination of shades of gray will look quite boring without a bright, accent on the attention, the colors. So color can be yellow - it will add color and give a "fresh" look gray room
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.
