Alteration of L*, C* coordinates for the microfaded samples in the central lantern. The black square marks the initial value, before fading, while the diamond marks the final value, after fading. The lightness of all samples decreases after fading. While the red, pink and orange sample desaturate, the chroma of the green samples keeps constant. Interestingly, the two violet samples have opposite behaviours, where chroma increases for V1, whereas it decreases for V2
