Cream is the pastel color of yellow, much as pink is to red. By mixing yellow and white, cream can be produced. Cream is the color of the cream produced by cattle grazing on natural pasture with plants rich in yellow carotenoid pigments, some of which are incorporated into the fresh milk (specifically, the butterfat). This gives a yellow tone to otherwise-white milk at higher fat concentrations (so the color of dairy cream could be considered partway between the colors of natural cow’s milk and butter) (Source: Wikipedia).
