Consider a set of colors in the LAB color space. lab = {LABColor[0.2, 0.5, 0.8], LABColor[0.6, -0.5, 0.2], LABColor[0.9, 0.5, -0.8]}; And the corresponding opacities are a={0.2,0.6,0.4}; How can I combine the colors and their corresponding opacities so that I get laba={LABColor[0.2, 0.5, 0.8,0.2], LABColor[0.6, -0.5, 0.2,0.6], LABColor[0.9, 0.5, -0.8,0.4]}Read more
