Discribe Isaac Newton's ground breaking color experiement in 1676?
He shined white light through a prism and found that light was all colors.
What did Newton's experiment reveal about the properties of white light?
That the individual components of white light are separate colors called hues which were: red, orange, yellow, green, blue, indigo, and violet.
The _________ Color System is the color system relevant to qpaque surfaces that reflect light.
Subtractive
The __________ Color System is the color system relevant to colored light.
Additive

Describe the color PINK in terms of its base hue plus tints or shades.
A tint of red
The three principle attributes of color are:

True or False? Visible light is part of the electromagnetic spectrum.
True
Within the human eye color is sensed by.
Cones
What does color temerature refer to? Example.
It refers to the colors on the wheel. Blue is a cool color, where red is a warm color.
Designing the lighting system for a theatre performance _______.

The teriary hues on the traditional subtractive color wheel are:
Yellow - Orange, Red - Orange, Red-Violet, Blue-Violet, Blue-green, Yellow-green.
_________ colors are hues located directly opposite from each other on the color wheel.
Complimentary
True or False? All pure base hues have the same value.
False
True or False? Primary colros are the same in an Additive-mixing situation as they are in a Subtractive-mixing situation.
False
True or False? In color theory terminology Intensity is the same as Saturation.
True
A base hue plus gray is called a _____.
tone
Describe the color MAROON in terms of its base hue plus tints or shades.
Shade of red
Describe the color BABY BLUE in terms of its base hue plus tints or shades.
tint of blue
To determine the base hue of particular color it is helpful to palce the color against what?
White, Black or neutral paper.
The three principle attribute of color.
Hue, value, saturation
When working with gouache what are at least two ways to adjust the intensity of a particular color?
water, add grey, black, or other colors.
A ______ is colored powder that imparts its color effect to a surface when distributed over that surface in a layer.
pigment
Name several binders commonly used in paint.
Oil, gum arabic, egg and acrylic.
Describe the difference between opaque and transparent.
You can not see through opaque, it completly covers the surface. Transparent lets white light through the surface.
How does a bitmap image differ from a vector image.
Bitmap is made up of pixels and a vector image is made up of line drawings with mathimatical geometric shapes.
What is a gradient according to your textbook?
Is a gradual blend of two colors.
Define in words an Analougous color scheme.
Three neighboring colors on the wheel.
Define in words 2 types of tetrad color schemes.
one would be a square which could be green, orange, red, and blue.
second would be a rectangle which could be yellow green, yellow orange, red violet, and blue violet.
Light/Dark value contrast
When placing a dark background with a light colro, it appears even lighter and vise versa.
Complementary reaction or effect (describe "bending")
An orange on a blue ground appears to have a higher saturation or intensity when compared to the same orange placed on a neutral gray gound. The complementary effect causes a color to bend toward the complementary color.
Color Subtraction
A strong or dominant color will actually subtract itself from a smaller or less dominant color.
YO-O=Y
RV on red and violet ground. RV on red looks more violet, RV on a vilet ground appears to be redder. RV-R=V, RV-V=R.
Afterimage
is cause by the fatigue in the hue sensors (cones) in our eye. It forces our eye to revert to the remaining hues. Example: stare at a red colored picture long enough then close your eyes and you will see the remaining complimentary colors our cones sense.
Optical Mixing
Creates a hue, value, or saturation change depending on what colors are mixed. Pin wheel affect, place two colors harmonies like yellow and orange when spun will create yellow-orange affect.
Triadic Harmony
Three hues that are of equal distance of eachother. Yellow, orange and violet.
Gradient
The blending of two colors
How can color create balance?
You can add balance to an unbalanced drawing through color. Making everything in the picture monochromatic reds. It can also be achieved by grouping complimentary colors in section of the drawing like blue and orange.
How can color create space?
Can be achieved by taking a bright yellow a putting that yellow image in the front as a focal point and receeding the image toward the back a slowly changing the color to a lower stauration by adding greys. As things get further back they become less saturated.
Mixing two complimentary colors creates what?
A neutral
Is violet higher or lower in value than green?
Lower
What is a vehical?
Water
What is the difference between Dyes and Inks?
Dyes are soluble colorants they transfer color by staining or absorbing into a given material.
Inks are dye based an water soluble. they are higher in colorfastness than dyes.
What is simulated transparency?
When two opaque colors overlap and seem to mix into a third color.
In order what are the gambits color system?
Human Visual System (highest)
RGB Monitor (Second)
CMYK (last)
What is relif printing?
Uses the raised and recessed areas of metal plates to form a prinited image.
Raised areas print and recessed stay white.
What is intaglio printing?
Are formed recessed areas. Plate is inked than wiped by hand to force the ink into the recessed areas.
The recessed areas print and the raised area stays white.
What is the gestalt theory?
the idea of the whole that is inseparable from its parts.
What is Achromatic harmony?
is a neutral containing no hue. Which means it uses all colors that are achromatic.
A double complementary scheme?
A four hue contrasting scheme. Like G and BG with O and RO.
A split complementary scheme?
a three hue color harmony which two hues are on either side of the actual complement chosen.
