  1. 1. COLORS By Swetha.K
  2. 2. PROPERTIES  Hue – Attribute by which we recognize color (eg red, blue, yellow etc)  Value – amount of lightness & darkness, by mixing white or black.  Intensity – Brightness or dullness of a color.
  3. 3. COLOR MIXING  Additive colors - An additive color model involves light emitted directly from a source or illuminant of some sort. The additive reproduction process usually uses red, green and blue light to produce the other colors. Combining one of these additive primary colors with another in equal amounts produces the additive secondary colors cyan, magenta, and yellow.  Subtractive colors - A subtractive color model explains the mixing of paints, dyes, inks, and natural colorants to create a full range of colors, each caused by subtracting (that is, absorbing) some wavelengths of light and reflecting the others. The color that a surface displays depends on which colors of the electromagnetic spectrum are reflected by it and therefore made visible.
  4. 4. TERMINOLOGY  Harmonious – colors adjacent to each other on the color wheel  Contrast / complementary – colors directly opposite to each other on color wheel  Achromatic – Any color that lacks strong chromatic content is said to be unsaturated, achromatic, or near neutral.  After image – a ghost image generated by the eye in response to stimulation by a single color in the absence of its compliment.
  5. 5.  Shade – pure color made darker with addition of black  Tint – pure color made lighter with addition of white.  Tone – pure color to which gray is added.
  6. 6. COLOR WHEEL  Primary colors – red blue yellow.  Secondary colors – obtained by mixing of 2 primary colors.  Tertiary colors – obtained by mixing of 2 secondary colors.  Warm & cool colors
  7. 7. COLOR SCHEMES  Monochromatic – one color in varying intensities  Complementary – directly opposite to each other on color wheel.  Double complementary – pair of complementary colors  Split complementary – one hue from one side of the color & the 2 hues adjacent to its complementary color.
  8. 8.  Analogous – 3 colors side by side  Triad/contrasting – equilateral triangle on color wheel  Tetrad – uses four colors evenly spaced on the color wheel
  9. 9. COLOR PERCEPTION  Color constancy – involves our tendency to compensate for the effect of various light sources on the color of the objects we see.  Simultaneous contrast – when 2 complementary colors are placed side by side, it tends to heighten each others saturation & brilliance without any apparent change in hue.  Optical mixture – when an objects patches of color are so small that they pass below the threshold of conscious perception, we see the colors as optically mixed.  Spatial dimension – when our brain add or subtract distance, depending upon the colors perceived.
