Existing perceptually uniform colour spaces such as CIE LUV and CIE LAB and their HCL transformation do not directly map in to the sRGB Colour space used by most image formats. In this paper I present a colour space based on angular hue that is approximately perceptually uniform, while being entirely contained by the sRGB colour cube. The new scheme was evaluated by comparing it to colour rendering systems used in the literature for electromagnetic fields, and was found to produce images that could be more intuitively interpreted.
