It’s a bird, it’s a plane...What is color?

Color is a perceptual sensation created in the human mind in response to certain wavelengths of electromagnetic energy that constitute the visible spectrum of light. Human perception of and response to these wavelenghts is affected by many factors including physiology, psychology, language, and culture.

› Color Design Workbook (Suggested reading for this class)

The quality of an object or substance with respect to light reflected by the object, usually determined visually by measurement of hue, saturation, and brightness of the reflected light.

› Dictionary.com

A phenomenon of light (as red, brown, pink, or gray) or visual perception that enables one to differentiate otherwise identical objects.

Technical DetailsdEfinition

Color is basically just a bunch of different wavelengths.

Humans can distinguish between these wavelengths and therefore we see the world in bright, beautiful color.

These wavelenghts come in all sorts of shapes and size, long wavelengths appear to us as red, while short wavelengths are violet.

Technical DetailsthE human color spacE

Our eyes have three types of color receptors: Red, Green and Blue. Therefore, everything we see is reduced to these colors or combinations of them.

Technical DetailsVisual spEctrum

The Visual Spectrum is a portion of the electromagnetic spectrum that is visible to the human eye.

Ultraviolet and Infrared fall outside of the Visual Spectrum.

There are 3 primary color systems that the designer needs to be aware of:

Additive or Pure Light Primaries (RGB)

Subtractive or Printer’s Primaries (CMY)

Subtractive or Artist’s Primaries (RYB)

Color in the Design Worldcolor systEms

Color in the Design WorldrgB color systEm

Additive or Pure Light Primaries (RGB)

RGB is Red, Green and Blue.

Since these 3 colors make up the Human Color Space, this color system is the most pure and has the most brightness or intesity. When these colors overlap, they create Cyan, Magenta, Yellow and White. White is acheived by seeing all colors.

This system is called Additive.

Color in the Design Worldcmy color systEm

Subtractive or Printer’s Primaries (CMY)

CMY is Cyan, Magenta and Yellow.

This system has physical properties that absorb color. For instance, the sensation of color is when the paper absorbs all wavelenghts except those that the eyes perceive. When these colors overlap, they create Red, Blue, Green and Black.

That is why this is called a Subtractive system, because it subtracts wavelengths.

Color in the Design WorldryB color systEm

Subtractive or Artist’s Primaries (RYB)

RYB is Red, Yellow and Blue.

RYB is the most common color system in art classes and is the basis for most color theory. This color system is similar to CMY where when all colors combined create black. When overlapped, they create Orange, Green and Purple.

This is also a Subtractive system.

My a-capella group was sweet!color harmoniEs

Color HarmoniescomplEmEntary

Complementary

Colors that are directly across from each other on the color wheel.

These colors have the most contrast and will excite the eye.

Color Harmoniessplit complEmEntary

Split Complementary

Three colors where one color is accompanied by two colors equadistant from its compliment.

Less contrast than complimentary colors, creating a more sophisticated look.

Color HarmoniesdouBlE complEmEntary

Double Complementary

A combination of two pairs of complimentary colors.

Using equal amounts of these four colors will be pretty intense and jarring.

Color Harmoniesanalogous

Analogous

Two or more colors spaced equally from each other.

Since they all have similar light wavelenghts, this color scheme is easy on the eyes.

Color Harmoniestriadic

Triadic

Three colors that are spaced evenly around the color wheel.

Some of these combinations can seem garish, while others are quite nice.

Color Harmoniesmonochromatic

Monochromatic

Made of shades or tints of the same color.

Low contrast and very pleasing to the eye.

Hue

The description of the dominant wavelength of a color.

Hue is also called the name of a color.

Properties of Colorsaturation

Saturation

A measure of the purity of the hue determined by the amount of gray it contains.

The more gray the color, the lower the saturation.

Saturation is also called chroma.

High Saturation

Mid Saturation

Low Saturation

Properties of ColorBrightnEss

Brightness

The amount of light reflected by a color.

The more light reflected, the whiter the color (white is all light reflected).

Brightness is also called value.

One of the most important decisions to make when choosing a paper is whether the paper is Uncoated or Coated.

Dot Pattern

Conventional offset print-ing lays down dots is a grid pattern, increasing and decreasing the size of dots to control density and color.

Stocastic printing uses a random dot placement and a random dot size.
