In this work an alternative color space is described that defines the color elements in terms of approximated brightness, hue and saturation, similar to other color spaces commonly used in computer applications. The classical color spaces such as HSL and HSV in the form that is widely used are made for convenience, and do not model colors based on human perception. Other classical color spaces such as CIELAB, DIN99 and even more recent CIECAM-based color spaces are too cumbersome and difficult to work with. The proposed alternative, on the other hand, is simple to work with and has its "lightness" component tuned up to represent the perceived brightness closer to the reality. It is based on how luma is calculated in color spaces such as YUV and YIQ among others, but instead of using constant coefficients, it uses Euclidean distance formula with weighting coefficients. Several experiments are described that illustrate the proposed color space visualized in 3D and compared to other color spaces in perceptual terms and performance benchmarks. This is aided by a novel technique that allows normalizing the chroma of existing color spaces within a fixed interval. The experiments show that the proposed color space is a viable alternative for applications that already use HSV and HSL. A practical application is described, where the color space is used for 3D illumination with specular reflections running on dedicated graphics processor unit using shaders. This resolves visual defects present in the classical approaches that use RGB color space.
