The Suphalak is a medium-sized, muscular cat with a head that features a modified wedge shape, medium width, and moderate length. Its coat is a rich and even shade of warm brown, more towards a red-brown rather than a black-brown, and does not display tabby markings. In the Tamra Maew, this color is referred to as 'thong daeng', resembling the color of copper. The whiskers are brown, complementing the coat, while the nose leather is a rosy-brown hue. Light brown paw pads with a pink tone complete the feet. The eyes of the Suphalak are a bright yellow/gold color, described in the Tamra Maew as shining and resembling sun rays.
