Shade

Adding black to a color makes it darker, creating shades. For example, adding black to red gives you a deeper maroon.

You can add varying amounts of black to any hue to create shades of that hue. They can range from a slightly darker version of the original color to a deep, nearly black tone that still retains some of the original hue.

Shades are used to add depth and contrast to designs, paintings, and drawings. They can create shadows, emphasize certain areas, or convey different moods.
