Colour images are much more than three bands of red, green and blue. The sensation of colour is the result of our sensing of the energy within the visible band from about 380nm to 730nm in wavelength. In order to capture the information required to reproduce the colour sensation of the objects under varying illuminations, we need an accurate spectral estimate obtained from measurements obtained by the camera. I will briefly review the colour science needed to understand what is needed for accurate colour capture. Then, I will discuss how sparsity and compressed sensing may be used to obtain the spectral estimates at the accuracy required for quality control of colour imaging applications.
