What is the longest wavelength color? The shortest?
Red is the longest and violet is the shortest.
How does the human eye see color?
The light reflected from an object enters the lens of an eye and is focused on the back wall of the eye, the retina, which is covered in nerve endings (rods). The rods register only degrees of black and white known as the TONAL quality of an object. This information is then sent to the brain for interpretation and where they are transformed into an image of the object.
"Color then is the ability of various wavelengths of light to enter the eye and stimulate appropriate color receptors to produce the sensation of color to the brain"
Color is a " " and not a " " property inherent in an object being veiwed
SENSATION
PHYSICAL
Physical objects interact with light to:
a) absorb some rays of white light while reflecting others (you see a red apple because it reflects red rays and absorbs all other colored rays)
What color in tonal order is the lightest in tonal quality? The darkest?
Yellow is lightest (at top) and purple is darkest or at bottom
What colors are not chroma colors and what are they called?
White, black, and grey are known as achromatic colors.
How do you measure for wallpaper?
Determine the entire distance around the room (2x length and 2x width) and multiply this number by height of walls in feet. This gives you the total SF. Divide this number by the number of SF in a roll. This gives you the number of rolls to order.
Define: Color harmony
The use of pleasing, balanced colors that work together to create a relationship of concord and agreement, giving a sense of order and visual pleasure.
Define: Color
A characteristic of light (aka radiant energy)
Define: Rainbow or the light spectrum
Red, orange, yellow, green, blue, indigo, and violet. The last two colors are so close to eachother that they are often merged and called purple, thus six colors are in some spectrums.
Define: TONAL quality of an object
degrees of black and white
Primary colors
These colors cannot be created by mixing any other combination of any other two or more colors. Red, Blue, Yellow
Secondary colors
A color resulting from mixing two primary colors in equal proportions. Green, Violet, Orange
Tertiary colors
Made by mixing equal parts of one primary color and one secondary color. Blue-green, Blue-violet, Red-orange, Red-violet, Yellow-orange, Yellow-green
The Munsell System
Allows for an infinite number of color variations using three characteristics of color and a notation system that clearly represents each in every possible color, even colors yet to be derived. The three components of color in the Munsell system are: hue, value, and chroma.
Define: Hue (another word for color)
The quality that gives an identifying name to a chromatic color so that we can distinguish one color from another. Munsell recognized five principal hues (red, yellow, blue, green, and purple) and five secondary colors (yellow-red, green-yellow, blue-green, purple-blue, red-purple.
Define: Value
The second characteristic of color. The term refers to the amount of light the color reflects (lighter toward white) and absorbs (darker toward black). Adding white or black to a color does not change the hue, only the lightness or darkness of a hue.
Define: Shades
A shade is a pure color to which only black as been added.
Define: Tint
A tint is a pure color to which only white has been added.
Define: Chroma
Refers to a color's intensity, purity, or saturation. In the Munsell color system, chroma is measured by the range of numbers from 1-14, with the highest numbers indicating maximum intensity. A low number such as two, indicates that the color is very grey and of low chroma. The more color, the higher the chroma number.
Define: Monochromatic colors
Are various tones of the same color, as you have seen on paint wheels. A monochromatic color scheme uses a single color (hue) in a wide or narrow range of chroma and value.
Define: Monotone
Color schemes use a single color of low chroma in one value or a very limited range of values, typically grays, tans, and tinted whites. (neutral)
Define: Tone or tonal
Tonal colors are different shades of colors of same main color group. Different tones of a color.
Define: Analogous colors
Use hues that are close together on the color wheel within an arc of no more than 90 degrees.
Define: Complementary colors
Are colors that appear opposite each other on the color wheel, such as red and green, blue and orange, and violet and yellow. Note that these are the three subtractive primaries (red, blue, and yellow) paired with the three secondary colors, green, orange, and violet, which are compliments.
Define: Split complimentaary
One of the most subtle and pleasing color schemes. In addition to the base color, it uses the two colors adjacent to its compliment.
Define: Triad colors
Three colors which are approximately equidistant from one another on the color wheel.
Define: Discordant colors
Occur when white or black is added to a color until its value is reversed. Also rare but interesting.
Define: Warm colors
Are near the red end of the color spectrum, including red, orange, and yellow
Define: Cool colors
Greens and blues
Violet color attributes?
May be warm or cool according to their content of warm or cool chromatic color.
Law of chromatic distribution
May help you decide on a color scheme. This principle states that the more neutralized colors of the color scheme should cover the larger areas.
Define: Simultaneous contrast
The term used to describe the effect that adjacent areas of color have on one another. This term also refers to the effect of size on color contrasts.
Define: Advancing and receding
Colors can be used to modify perception and spatial relations. Warm colors appear closer than they are and cool colors recede.
Different colors in small areas
Fuse or mix when seen at a distance. A textile woven of two color yarns will seem to be one solid color from a distance.
Beware of metameric shift
The appearance of an object or textile as one color in one light and another color in another light.
