Light and Color Sayre – 7th edition Chapter 6
Actual light • Can be natural or artificial light • 3D sculpture and architecture
Value • the relative lightness and darkness of surfaces (it is a range and is viewed in relationship to what is around it)
Two examples of the use of value: Chiaroscuro – the use of gradations of light and shade, in which forms are revealed by the subtle shifting from light to dark areas Tenebrism – sharp contrast between areas of light and dark (creates spotlight effect)
ROYGBIV Now for a little science review… • 1666 Sir Isaac Newton: “white” light is actually composed of all the colors of the spectrum (ROYGBIV) • when you pass light through a prism it separates into different bands of color; because each color has a different wavelength, each travels at different speeds; so the color sequence remains constant
Primary colors – hues that cannot be produced by mixing other hues
Secondary colors – mixture of 2 primaries will give you a secondary
Intermediate (a.k.a. tertiary) colors – mixture of one primary and one secondary
Color Vocabulary • Achromatic – without the property of color (a.k.a. hue); not true colors; neutrals (grey, black, white) • Intensity (a.k.a. saturation) – the relative purity of a color/hue
Shade – black added to a color/hue produces a shade of that color/hue • Tint – white added to a hue produces a tint of that hue
Color schemes • Analogous – colors adjacent to each other on the color wheel ***(think temperature) • Complementary – emphasis on two hues opposite one another on the color wheel
***Cool vs. warm colors • Cool colors – blue/green side of the color wheel appear to contract and recede • Warm colors – red/orange side of the color wheel appear to expand and advance
