A tint, or shade, refers to a variation of a color created by adding white to the original hue. This process lightens the color, resulting in a softer and often more pastel appearance. For example, adding white to red produces pink, which is a tint of red. Tints are commonly used in art and design to create depth and visual interest. In contrast, a shade is created by adding black to a color, making it darker. This technique can enhance the richness of a color, such as turning blue into navy blue. Both tints and shades are essential in color theory, helping artists and designers achieve desired effects in their work.
