Presentation Transcript

  1. Light and Color Sayre – 7th edition Chapter 6

  2. Light

  3. Actual light • Can be natural or artificial light • 3D sculpture and architecture

  4. Sculpture (fig 394/13-34) *see Turrell’s work at the MFAH

  5. Implied Light

  6. Value • the relative lightness and darkness of surfaces (it is a range and is viewed in relationship to what is around it)

  7. 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)

  8. Figs 288/11-9 and 289/11-10

  9. Fig 282/11-3

  10. Fig 124/6-7

  11. Fig 271/10-27

  12. Color

  13. 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

  14. Color Wheel (the spectrum reorganized)

  15. Primary colors – hues that cannot be produced by mixing other hues

  16. Secondary colors – mixture of 2 primaries will give you a secondary

  17. Intermediate (a.k.a. tertiary) colors – mixture of one primary and one secondary

  18. 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

  19. 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

  20. 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

  21. ***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

  22. Analogous (fig 686/21-1)

  23. Analogous (fig 143/6-29)

  24. Complementary (fig 145/6-31)

  25. Complementary (fig 690/21-5)
