Mixing the colors brown and yellow will make what is described as a lighter and brighter shade of brown. Yellow is one of the primary colors used to make brown.
There are three primary colors from which all other colors are derived. These colors are red, blue and yellow. The primary colors combine to create the secondary colors: purple, green and orange.Brown is produced by mixing orange (a mixture of red and yellow) with blue. Adding more yellow will tint the brown but not alter its place color wheel because brown inherently possess a level of yellow mixed into it.
