About My goal was to provide the best possible color combinations to differentiate things for the entire humanity. Being a deuteranop myself, I felt the soft discrimination during all my life. When someone with normal color vision figures out some color coding, he or she rarely thinks on making it differ- entiable for the minority who has some kind of color blindness. Lights, signs, panels, wires, maps, charts, tools, games... many items are hard to differentiate for someone with color vision defficiency. Please start thinking on making things properly visible for them as well! Hence these palettes. The CVF palettes have the highest possible perceived difference property in the sRGB color space for the number of colors they represent, considering all types of color visions: • Normal vision • Deuteranopia • Protanopia • Tritanopia • Achromatopsia The first order of optimization was done by achromatopsia. That resulted the GRAYSCALE Palette Collection which is the basis of all CVF palettes. For the second order of optimization all color visions were weighted equally. This is a new approach for making color blind frienly palettes. Former authors optimized only for the most common defficiencies, deuteranopia and protanopia. The palettes contain increasing number of colors from black to white inclusive. The intermediate colors are evaluated using an industry standard method to maximize the perceived difference of the palettes. For each number of colors there is an assortment of palettes to choose from with the top one being the best but none being below 90% from the best in terms of color differentiation quality.
