How do you make vermillion color?

Vermilion is a bright red to reddish-orange pigment traditionally made by grinding cinnabar, a Mercury sulfide mineral. In modern times, it can also be created by mixing a bright red pigment, like cadmium red, with a small amount of yellow, such as cadmium yellow or a similar hue. Adjusting the proportions can help achieve the desired shade of vermilion. Always handle pigments with care, especially those that may be toxic, such as traditional vermilion.
