If you sell products with complex tints and shades of color, for effective UX, show your customers all the available colors, even if they are similar. To do so, use color families.

Like in the example below, the shirt has two pretty close shades: blue and cyan. Although they look similar, both are displayed in swatches. If you want to find out more about how color families work and set them up, refer to our documentation
