What is hue?
|
The visible property of colors as determined by the dominant wavelength of the light. In simpler terms: the name of the color you see. Photoshop assigns a numerical value to combine different percentages of RGB light into different hues
|
|
|
What are the two generic color models based on?
|
The way light is transmitted.
|
|
|
What is a color model?
|
The method of defining or modifying color.
|
|
|
What are the acronyms for the two generic color models and what do they stand for?
|
RGB and CMYK. RGB stands for Red-Green-Blue. CMYK stands for Cyan-Magenta-Yellow-Black.
|
|
|
What is color value?
|
The tonal value of a color when related to a light-to-dark scale of pure grays.
|
|
|
What is lightness?
|
The tonal measure of a color relative to a scale running from black to white. Also called "brightness" or "value."
|
|
|
What is the subtractive color model?
|
The color model describing the primary colors of reflected light: cyan, magenta, and yellow. The subtractive colors, plus black, for the basis for printed process colors.
|
|
|
What is a color management system and what is its purpose?
|
Not all colors in the visible spectrum are achievable by all devices. Color gamuts from various devices may not match exactly. For example, many of the colors displayed on a monitor cannot be printed on a 4-color press. Color management systems maintain consistency of color gamuts across various devices.
|
|
|
Which color model is "subtractive" and what does "subtractive" mean?
|
CMYK. The subtractive color model is based on the absorption (i.e. subtraction) and reflection of light. For example, with printed inks - if you subtract (remove) 100% values of either red, green or blue from white light, you create cyan, magenta, or yellow.
|
|
|
What is color gamut?
|
Describes the full range of colors achievable by any single device on the reproduction chain.
|
|
|
What is color?
|
The visual interpretation of the various wavelengths of reflected or refracted light.
|
|
|
Which color model is "additive" and what does "additive" mean?
|
Additive means adding or combining the three colors RGB in various proportions. The additive color model is used in computer monitors, which transmit varying proportions of red, green and blue light which we interpret as different colors. By combining varying intensities of RFB light we can simulate the range of colors found in nature. When 100% of all values are combined, we preceive white. When 0% of all colors are combined, we see no light or black.
|
|
|
What is the additive color model?
|
The color model describing the primary colors of transmitted light: red, green and blue (RGB). Additive colors can be mixed to form all other colors in photographic reproduction and computer display monitors.
|
|
|
What is saturation?
|
The intensity of the hue displayed. A fully saturated image has the color "volume" turned all the way up resulting in extremely "loud colors", a desaturated image is shades of black, white & gray.
|
|
|
What is brightness?
|
The amount of how much white or black is mixed into the color. Increasing the brightness in Photoshop will "fade" the image, decreasing the brightness will make the image darker
|
|
|
What is contrast?
|
The range between the darkest pixels and the lightest pixels. Increasing the contrast causes highlights to appear lighter and shadows to appear darker.
