The Colormaking Attributes. We live in a culture awash with color of every kind digital color, print color, photographic color, inks, paints, dyes, fabrics, cosmetics, gems, leathers, metals, flowers, foods, cars, ceramics. For our purposes, we want a color language that is both compact and unambiguous. Surprisingly, just three attributes adequately describe all color experience, provided we ignore the material qualities of color such as surface texture, mottling, iridescence, translucency or gloss. These three attributes are the colormaking attributes of lightness, hue and chroma. Eros Ramazzotti 9 Rar. Lightness is the light or dark quality of a surface color relative to a pure white surface. The white surface is the visual benchmark for how much light is falling on all surfaces under the same illumination for example, all the objects in a landscape under the sun, or all the objects in an office under ceiling lights.

The example below shows variations in lightness, which we describe as variation from dark to light color variation in lightness onlyhue and chroma held constant. Painters often call lightness the value of a color, following the 1. We provide excellent essay writing service 247.

What happens if a color appears brighter than the illumination seems able to produceIf the excess lightness is relatively small then the color will color appear to luminesce or glow. If the excess is large then the surface will appear to be emitting light, and we describe the color as a perception of brightness in relation to the average light or dark to which our eyes have become adapted. In the photograph above, top, the color of the white sheet in light, when viewed in shadow, is about 4 times brighter than the sheet appears in the original photograph. This makes it appear to glow with a light of its own. Since we are only concerned with paint colors, the terms lightness or value, modified by dark,middle or light, are used to describe lightness variations. Hue is the color of a color, the name for any color found within the prismatic light spectrum red, orange, yellow, green, cyan, blue, violet or in the extraspectral hues made by overlapping the opposite ends of two spectra purple, magenta. To simplify and standaridize the way we talk about color, hue names are limited to a small number of spectral categories red, orange, yellow, green, blue and violet. These are the six fundamental hue categories color variation in hue onlylightness and chroma held constant. In a prismatic spectrum the hues imperceptibly blend from one into another. To capture some of this variety, compound names can be made by joining the names of neighbor or blended spectral hues violet red, yellow green, green blue or by joining a spectral name with a lightness qualifier light yellow, dark red, middle green. This creates eighteen compound hue categories and 5. Search the worlds information, including webpages, images, videos and more.

Hue purity is amount of pure hue in the color in proportion to the amount of white, gray or black that is mixed with it. It turns out that pure hue can be defined in several ways, and several terms are used to describe it. The technical term for hue purity for example, in the Munsell Color System is chroma, and the common visual judgment is saturation, which is the amount of chroma in a color relative to its lightness in surface colors or brightness in lights. Ppf O Matic Patch Xbox 360. Colors that contain no hue, and therefore appear white, gray or black, are termed neutral or achromatic. The example below shows the variation in a red hue from neutral to intense. The purest hue possible in a physical color is found in a very narrow section of a prismatic spectrum or the light of a monochromatic laser. The colors of physical surfaces which always absorb some of the light falling on them, and reflect the rest will always appear to contain some quantity of white or black, and therefore all surface colors including paints appear less saturated than spectral lights or transmitting materials such as stained glass. There is no standard terminology for gradations in chroma, but here i will use intense to mean the highest chroma possible in paints, with subdued,dull and gray to represent gradations to a neutral value. These 4 gradations create 2. These three terms allow for an accurate, unambiguous description of color. Whenever possible, avoid impressionistic or metaphorical color descriptions such as dingy, luminous, rich, bold, subdued or brilliant unless you want to be impressionistic and metaphorical.
