sensitive to the three dimensions. Hue is gen erally the most critical. followed by chroma. and finally lightness. Muns is a well-known color-order system that specifies surface color and has found wide acceptance in a diversity of color applications. Munsell identifies the hue value (lightness). and chroma (saturation) of a color using color chips of equal visual spacing (Fig. F5.1.1.). The chips are arranged on pages in a book. All the chips on a single page are the same hue, but they vary in value and chroma The observer chooses the chip that best matches the color of the object being evaluated. The chip selected will have a notation that identifies the assigned hue, value. and chroma. Visual color standards like Munsell have long been used in various food applications to specify color The subject of color. as it relates to the human eye and brain. is complex and fascinat ing. Overall. there are many factors that can affect the perceived color of a surface. Model like Munsell use an alphanumeric notation to identify the dimensions for a color and its
