The Colour 02 (Hex Value F3631B) doesn’t have a high enough contrast to be used as the brand dark colour, as some components display it against a white background. When displayed against a white background, the colour has a contrast of 3.17:1 , failing to meet the 4.5 ratio required for text. It does just about meet the ratio required for graphical objects though.
