The typical paint scheme for Harlequins in Warhammer 40,000 is characterized by bright, bold colors and intricate patterns. The colors and patterns are often symbolic and can convey different meanings depending on the context. The most common colors used are black, white, and various shades of purple, blue, and red. The black areas of the armor are typically used to create contrast and provide a background for the other colors. The white areas are often used to create a stark contrast with the other colors and to emphasize the intricate details and patterns of the armor. The purple, blue, and red areas are used to create a striking, vibrant, and eye-catching appearance. The patterns on the armor are often geometric in nature and can include shapes such as diamonds, triangles, and circles. Some Harlequins also have the symbol of their faction, the Laughing God, on their armor. It's worth noting that Harlequins are known to be very creative, and so many players will have different variations and interpretations of the paint schemes.
