Colors depend on our perception and this can vary from one subject to another. Thus, over time, various methods were born to make the classification objective, to define colors based on coordinates, with standardized light. In the major graphics software there are chromatic coordinates (HEX, RGB, CMYK e HSV) that allow us to better orient ourselves. In the case of red, eg, we can distinguish: magenta, the scarlet, the vermilion, the cinnabar, the red lead, coral, cadmium, the crèmisi, il pompeiano, the purple, the carmine, amaranth, the grenade, it burgundy, the cherry, the terracotta, the Venetian, the Titian, the Valentino, the Ferrari and others.
