Call them what you want - Spanish tiles, Moroccan tiles, patchwork tiles, boho tiles - whatever term you use for these floor tiles there's no denying just how immensely popular they have become in recent years.
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
Black and white is a traditional color scheme, obviously, but adding red into the mix just requires the colors to a completely new degree of energy. Black is best utilised in little doses as an accent. Somewhat black will go a ways.
