How Do Your Eyes See Color? Video
• Light waves that have been emitted (released) or reflec ted by an object, enter the eye and first pass through the transparent layer called the cornea where they are refracted. • The light rays are then refracted again as they pass through the transparent lens (convex). • The lens focuses the light waves on the retina, located on the back of the inside of the eye. • The retina is composed of tiny light sensitive nerves that transfer the energy of the light waves to nerve impulses transmitted through the optic nerve to the brain for
The absorption and reflection of light waves by various materials results in human perception of color as follows: • Most materials absorb light of some frequencies and reflect the rest. • If a material absorbs a certain frequency of light, that frequency will not be reflected, so its color will not be perceived by the observer. • If the material does not absorb a certain frequency of light, that frequency will be reflected, so its color will be perceived by the observer. • If all colors of light are reflected by a material, it will appear white. • If all colors of light are absorbed by a material, it will appear black.
Colours of light
How Is A Rainbow Formed at home The Light Spectrum
Color • Has three properties: – Hue • the name of the color (such as red, blue, etc).
– Intensity • The purity of strength of the color such as the brightness or dullness.
– Value • The lightness or darkness of the color.
Chromatic and Achromatic Colors WHITE AND BLACK
black and white are called achromatic colors, as they lack color. they are not present in the Itten color circle. a. White is the sum of all the colors forming the spectrum of light (which, in fact, appears white to us). b. Black is determined by the lack of colors: no object, in the dark it is colored.

THE COLOR WHEEL The color wheel is the colour spectrum bend into a circle. The acronym rgb represents the colours in the colours in the color spectrum. RED - ORANGE - YELLOW GREEN - BLUE – VIOLET Specific color on the color wheel had specific designation
PRIMARY COLOR Why they are called primary? These colors are called primary because they are used to mix all of the other colors in existence. Red yellow , and blue are formed by a pigment and cannot be made by mixing any colors together.
Yellow Red Blue
SECONDARY COLOR Are colors that are created by mixing equal parts of a secondary color with a primary colors.
Yellow Orange
Green
Red
Blue
These colors are orange, green, and violet (purple). Red + yellow = Orange Blue + yellow = Green Blue + red = Violet
Purple (violet)
INTERMEDIATE/TERTIARY COLOR Are created by mixing equal parts of a secondary color with a primary color.
These colors are Red - orange, yellow – orange, red – violet, blue – violet, blue – green, and yellow - green. Tertiary colors are named according to the colors that are used to mix them, listing the primary color first.

COLOR VALUE Refers to the lightness or darkness of a color. In color wheel each color is represented with a full range of value. When neutral colors (also called neutral) are mixed with colors on the color wheel, the value and/or intensity of the color is affected.
COLOR VALUE Tints are created by adding white to a color (ex: a tint of blue) Shade are created by adding black to a color (ex: a darker shade of blue)
COLOR VALUE Each color (hue), when mixed with white or black can produce a full range of Value
Intensity, although related to value is slightly different. Color intensity is adjusted by adding grays to the hue
COLOR SCHEMES Color schemes are systematic ways that colors are put together in artworks according to their arrangement on the color wheel. Knowledge of arrangements of colors or schemes can help an artist make informed decisions about color their own Also called «palettes» artworks. Monochromatic schemes consist of just one color and the tints and shades (Values) of that color. «Mono» means one and «chroma» refers to color. Monochromatic literally means « one color». A Monochromatic Color Scheme is where one color is used but in different values and intensities.
