Note on the left the Indication of the three zones, Light, Middle, Dark and on the right the notation of NEUTRAL at the various levels of VALUE. This variable light strength is called VALUE, most Yellows being rather high in VALUE, and most Purple-Blues being rather low in VALUE, although of course Yellow can be very dark and Purple-Blue can be very light.ĭiagram of the VALUE scale. Purple-Blue is a dark color, nearer to Black than to White. For instance, Yellow is usually a light color, nearer to White than to Black. But between the two can be distinguished various degrees of light strength, ranging from the darkest gray just above Black to the lightest gray just below White, and color can be seen at these various intermediate levels of light strength. Pure Black is so dark that no color can be seen in it. Pure White is so light that no color can be seen in it. In notating a color, its HUE is indicated by the initial letter or letters of the color referred to - R for Red, YR for Yellow-Red, Y for Yellow, etc. It is how we know, for instance, that a Red is Red and not Green or any other color but Red. HUE is the first characteristic of a color that the eye detects. Any RED is Red in HUE, and any Green is a Green HUE, etc. Passing a ray of sunlight through a prism breaks the light up into a band (the spectrum) of its component colors, Red, Yellow, Green, Blue, etc., and this distinguishing by name of any color of the spectrum from the other colors, indicates the HUE, or common name, of that color. Sunlight is composed of every possible spectrally pure color, so balanced in combination that no one color is dominant and the result is a pure white light. Each of these dimensions of color can easily be measured (at a glance, with practice) and stated simply in speech and writing.
This section of the 1st edition of the Munsell Book of Color from 1929 discusses the three dimensions of color: Hue, Value and Chroma.Ĭolor had three dimensions, HUE, VALUE and CHROMA, which fully and accurately describe any color as readily as the three dimensions of a box describe its length, breadth, and thickness.
