The majority of diamonds will have tints of brown or yellow, but diamonds can be found in almost every colour of the spectrum. The term Diamond Colour commonly refers to the absence of colour, which is a facet of quality along with the other 4Cs of Diamond Cut, Diamond Carat Weight, and Diamond Clarity.
Yellow and brown diamonds that show more colour than the Z grade within the D-Z colour scale are termed fancy colours. Since the majority of diamonds have a bit of brown or yellow tint, any other colours apart from those hues are called fancy colours. These include orange, red, pink, black, green, and blue diamonds
