Yellow is one of three primary colors, which means that it is one color only and cannot be made by mixing other colors. The shade of yellow may be lightened or darkened by adding additional colors, however. White can be added to yellow to make a paler shade, and adding orange or red will create a darker yellow.
Color saturation determines how certain hue will look in certain lighting conditions. For example, a wall painted with a solid color will look different during the day than it does at night. Because of the light, the saturation of the wall will change over the course of day, although it is still the same color. When the saturation is zero, what you will see is a shade of gray.
