Colour and Munsell colour system

Colour is a phenomenon of light.
Colour induces different feelings in individuals according to the environment.
Colour alters the appearance of object.
Colour is one of the most powerful of elements and has tremendous expressive qualities.

2. Ø The word colour applies to the whole spectrum - red, orange, yellow, green, blue,
violet, black and white.
ØThe colour wheel or colour circle is the basic tool for combining colours. The first
circular colour diagram was designed by Sir Isaac Newton in 1666. The color wheel is
a means of organizing the colors in the spectrum. The color wheel consists of 12 sections.
Ø Colour is a phenomenon of light.
Ø Colour induces different feelings in individuals according to
the environment.
Ø Colour alters the appearance of object.
Ø Colour is one of the most powerful of elements and has
tremendous expressive qualities.
Ø Each color is made up of a single wavelength combined to form
other colors. For example, red light mixed with yellow light creates
an orange color.
Ø Color is the most important, versatile, and distinctive of the
elements of design.
Ø Color is almost always the first thing you notice when entering a
room.
Ø Color can set a mood.
Ø Color can make rooms feel larger or smaller.
Ø Color can even hide architectural flaws.

3. ØThe secondary colors are orange, green and violet and are duller than the primaries because they have been
mixed together.
ØThey form a triangle on the color wheel and are colors that are mixed from the primary colors.
ØPrimary + Primary = secondary - orange green violet, Red + yellow=orange, Blue + yellow= green, Red +
blue= violet
T
Ø Primary ,Secondary and Tertiary colors.
ØThe primary colors are, red, yellow and blue and are the purest and most intense
of all the colors.
ØThey form a triangle on the color wheel and are colors that cannot be mixed from
any other colors.
ØThese are the only colors that can be found in nature.
ØThe Intermediate (Tertiary) Colors -These colors are yellow-orange, yellow-green, blue-green, blue-violet,
red-orange, red-violet and are even duller than the secondary colors because the primary has been mixed with
a secondary.
ØThese 6 colors are formed by mixing a primary and a secondary color.
ØPrimary + Secondary = Tertiary, yellow + orange=yellow-orange, yellow + green = yellow-green, blue + green
=blue-green, blue + violet = blue-violet, red + violet =red-violet, red + orange = red-orange, Yellow orange Red
orange Red violet Blue violet Blue green Yellow green

4. ØThe concept of RGB (Red, green, Blue) and RYB (Red Yellow, Blue) is the perspective at which light comes to you.
ØAdditive color systems
start without light
(BLACK).
ØLight sources of various
wavelengths combine to
make a color.
ØResultant colour is white.
ØIs what happens when
lights of different
wavelengths ( colours) are
mixed.
ØFor light.
ØFor scientific purposes.
ØSubtractive color systems
start with light (WHITE).
ØColored inks, paints, or
filters between the viewer
and the light sources of
reflective surfae subtract
wavelengths from the light,
giving it color.
ØResultant colour is black.
ØAll the colours
( wavelengths) except the
visible one have been
absorbed ( subtracted )
ØFor pigment.
ØFor artistic purposes.
ØBlack absorbs most light.
ØWhite reflects most light.

5. ØA hue is the purest or brightest form of a color.
ØHues are colors that have not been mixed with white, gray, or black.
ØThe twelve colors around on the outermost part of the wheel are hues.
ØThe circle of colors next to the hues
represent the tint of each hue.
ØA tint is the hue mixed with white.
ØThe next circle of colors next
to the tint represent the tone
of each hue.
ØA tone is the hue mixed with
gray.
ØThe inner circle of colors next to the
tone represent the shade of each hue.
ØA shade is the hue mixed with black.
ØThe art element that describes the darkness or lightness of a color.
ØQuality of brightness and purity three properties.
ØHigh intensity -color is strong and brigh.
ØLow intensity -color is faint and dull three properties.

6. Ø“ Mono” means “one”, “chroma” means “color”… monochromatic color schemes have only
one color and its values.
ØUtilizes colors from the same family on the wheel.

ØComplementary colors are opposite on the color wheel provided a high contrast .
ØUse three colors that are eqyally spaced from each other on the color wheel .
ØUse three colors that are eqyally spaced from each other on the color wheel .
ØUse two colors on either side of colors complement.
ØUseing colors that are next to each other and then finding their opposites on
the colour wheel.
ØAre energetic and stimulate activity. ØAre relaxation and calm.

7. Øthe Munsell color system is a color space that specifies colors based on three properties of
color : hue, value (lightness), and chroma (color purity).
Ø the first to systematically illustrate the colors in three-dimensional space.
Øis based on rigorous measurements of human subjects’ visual responses to color.
ØThe system consists of three independent properties of color which can be represented
cylindrically in three dimensions as an irregular color solid: hue, measured by degrees
around horizontal circles; chroma, measured radially outward from the neutral (gray)
vertical axis; and value, measured vertically on the core cylinder from 0 (black) to 10
(white).
ØPlain white and plain black at the two ends
of the center axis
ØGrays range from light to dark along the
center axis
ØNeutral tones, with less chroma, near the
center of each spoke of the wheel
ØStrongest “chroma” of each hue, found
toward the outer edge of the ring
