Transcript

  • 1. Color
  • 2. Color• Color is the visual effect that is caused by the spectral composition of the light emitted, transmitted, or reflected by objects.
  • 3. Color originates in light. Sunlight, as we perceive it, looks colorless.In reality, all the colors of the spectrum are present in white light.
  • 4. 1. All the" invisible" colors of sunlight shine on the apple.2. The surface of a red apple absorbs all the colored light rays, except for those corresponding to red, and reflects this color to the human eye.3. The eye receives the reflected red light and sends a message to the brain.
  • 5. When light hits the surface, the BLUEpaint ABSORBS all thelight EXCEPT the blue part of the spectrum.
  • 6. There is no pure blue.
  • 7. If colored paints were actually pure color- every time any two “pure” colors of paint were mixed you would get.................. .... . . .. . ... .... black. The bits of blue in the blue paint would ........... ..... .. .... .. .. ... .......... .................. . . . .. ..... ............ ... ..... . .. .. ... ... .... ... .. ... ... .. . .... absorb the red and yellow light. The bits of yellow paint would absorb ... .. .. .. ... ............................ .......... .. . ...... . . .... .. ... the red and blue light. No light would escape from the paint, .. . .. ... . . .. .... . .. and you’d see a perfectly black surface.
  • 8. Itten Color Wheel
  • 9. Color Bias Wheel
  • 10. How to use the color bias wheel to mix colors...
  • 11. What happens when you mix complementary colors? + + +
  • 12. What happens when you mix complementary colors? + = a neutral + grey or brown +
  • 13. Color Bias Wheel
  • 14. make brightest purple
  • 15. make duller purple because some blueand orange are mixed
  • 16. make dullest purple,because blue is mixed with orange and red is mixed with green.
  • 17. Color Bias Wheel
  • 18. Properties of Color•HUE• VALUE• INTENSITY (or saturation)
  • 19. Properties of Color• HUE - the name of the color, the part of the color spectrum that the color belongs to: Red, orange, yellow, green, blue, or violet.
  • 20. Itten Color Wheel
  • 21. Local Color• the natural color of an object unmodified by adding light and shadow
  • 22. Local Color
  • 23. Properties of Color• VALUE - lightness or darkness of the hue.
  • 24. MUNSELL VALUES
  • 25. “Normal” hues have different values.
  • 26. Properties of Color• VALUE - lightness or darkness of the hue.• adding white produces a TINT• adding black produces a SHADE
  • 27. “ “
  • 28. Properties of Color• INTENSITY - the brightness of a color. Not to be confused with lightness, which is value.• also called “chroma” or “saturation”.
  • 29. Adding a color’scomplement willmake that colorLESS INTENSE.
  • 30. Color Bias Wheel
  • 31. Shadows in black and white...
  • 32. Shadows in black and white... 6 7-8 3 3 2-34-5 1 3
  • 33. SHADOWS of COLORS are made by adding that color’s COMPLEMENT.
  • 34. Here, thePink Cube Red Cube shadowed side is more intense than the others. Only a transparent material could look like this.
  • 35. The cube’s SHADOWED sidemust be LESS INTENSE than the cube’s brightly-lit side.
  • 36. “Color obtains in the light” -Thomas Lovell ???
  • 37. “Color obtains in the light” -Thomas LovellIn other words:Color becomes more saturated when it’s in the light.
  • 38. Vermeer
  • 39. Jacque Louis David
  • 40. Edward Hopper
  • 41. Sometimes painters take this a stepbeyond, and paint the shadows as the complementary color itself...
  • 42. yellow purple
  • 43. yellow orange purple blue
  • 44. WayneTheibaud
  • 45. Sometimes colorreflects from one object onto another...
  • 46. Reflected color...
  • 47. Bonnard
  • 48. Bonnard
  • 49. SIMULTANEOUS CONTRAST when the color’s complement is placednext to the color, it will look more intense.
  • 50. Bonnard
  • 51. Other kinds of simultaneous contrast...
  • 52. Other kinds of simultaneous contrast...VALUE - a color will appear darker in value on a light ground and lighter on a dark ground
  • 53. Other kinds of simultaneous contrast...
  • 54. Other kinds of simultaneous contrast...INTENSITY - A color will appear more intense on a more neutral ground and grayer on a very intense ground
  • 55. Other kinds of simultaneous contrast...
  • 56. Other kinds of simultaneous contrast...HUE - Orange will look more orange on a field of red and more red on a field of yellow.
  • 57. Josef Albers - Homage to the Square
  • 58. Victor Vasarely
  • 59. Properties of Color• HUE• VALUE• INTENSITY (or or saturation)
