This document discusses properties of color including hue, value, and intensity. It describes additive and subtractive color mixing. Key terms like harmonious, complementary, and achromatic colors are defined. The color wheel is explained showing primary, secondary, tertiary, warm and cool colors. Different color schemes are outlined such as monochromatic, complementary, analogous, and triadic. Color perception topics like color constancy, simultaneous contrast, and optical mixture are covered. Finally, the psychological effects of different colors like red, blue, green, and black are summarized.

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. 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. 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.  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. 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. 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.  Analogous – 3 colors
side by side
 Triad/contrasting –
equilateral triangle on
color wheel
 Tetrad – uses four
colors evenly spaced
on the color wheel

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.
