How the Eyes See Color

Color originates in light. Sunlight, as we
perceive it, is colorless. A rainbow is proof that
all the colors of the spectrum are present in
white light. As illustrated in the following
diagram, light goes from the source (the sun) to
the object (the apple), and finally to the detector
(the eye and brain).

Diagram of How the Eyes See Color
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.

Color Spectrum

Color Spectrum- bands of color
produced when white light passes
through a prism and is broken into
separate wavelengths; Color always
appears in the same order, by
wavelengths from shortest to longest:
red, orange, yellow, green, blue, violet.
A rainbow is a natural example of a
spectrum.

The Color Wheel

The color spectrum bent into a circle,
the color wheel is a useful tool for
organizing colors.

Color Properties:
Hue, Value Intensity

Hue- The name of a spectral color

Value- The lightness or darkness of a color. The color
value of any hue can be altered by adding black or
white.
Shade- a dark value
of a hue made by
adding black.
Tint- a light value of a
hue made of a hue
made by adding white
Chiraroscuro- The use of value contrasts to
represent the effects of light and shadow

Color Properties:
Hue, Value Intensity cont’d



Intensity (saturation)- the brightness
or dullness of a hue
a pure hue is high-intensity
a dulled hue, or a color mixed with it’s
complement is a low-intensity color

Color Harmonies


Also referred to as color schemes, they
are combinations of colors that are
considered satisfying.
Each scheme creates a particular visual
effect

Color Harmonies
Harmony can be defined as a pleasing arrangement of parts,
whether it be music, poetry, color, or even an ice cream
sundae.
In visual experiences, harmony is something that is pleasing to
the eye. It engages the viewer and it creates an inner sense of
order, a balance in the visual experience. When something is
not harmonious, it's either boring or chaotic. At one extreme is a
visual experience that is so bland that the viewer is not
engaged. The human brain will reject under-stimulating
information. At the other extreme is a visual experience that is
so overdone, so chaotic that the viewer can't stand to look at it.
The human brain rejects what it cannot organize, what it cannot
understand. The visual task requires that we present a logical
structure. Color harmony delivers visual interest and a sense of
order.

Color Harmonies
Therefore, extreme unity leads to under-stimulation,
or blandness, extreme complexity leads to overstimulation, or chaos. Harmony is a dynamic
equilibrium.

PRIMARY COLORS
Red, Yellow and Blue
These are the 3 pigment colors that cannot be mixed or
formed by any combination of other colors. All other
colors are derived from these 3 hues.

SECONDARY COLORS
Green, Orange and Violet
These are the colors formed by mixing
the primary colors. They are in between
the primary colors on the color wheel.

INTERMEDIATE COLORS
Yellow-orange, red-orange, red-purple,
blue-purple, blue-green and yellow-green.
These are the colors formed by mixing primary
colors with secondary colors. They are located
between the primary and secondary colors on
the color wheel.

A color scheme based on analogous colors
Analogous colors are adjacent, or side
by-side on the color wheel, such as yellow
green, yellow, and yellow-orange.

Color Harmonies cont’d
A color scheme based on complementary colors
Complementary colors are any two colors that
are directly opposite each other, such as red and
green and red-violet and yellow-green. In the
illustration above, there are several variations of
yellow-green in the leaves and several variations of
red-violet in the orchid. These opposing colors create
maximum
contrast and maximum stability.

Split Compliments- One hue combined with
each side of its compliment:
Red, yellow-green,
blue-green

A color scheme based on nature
Nature provides a perfect departure point for color
harmony. In the illustration above, red yellow and green
create a harmonious design, regardless of whether this
combination fits into a technical formula for color
harmony.
