1. Color

2. What exactly is color?
Simply put, color is what we see when light is reflected off of an object. Color consists of three major properties: Hue (the name of the color such as red, blue, yellow), intensity (which is the purity of the color), and value (which is the light and darkness of the color).

3. Primary Colors
As we all know, the primary colors are red, yellow, and blue. Do you know why they are the primary colors?
These three colors are called the primary colors because they are the only colors that cannot be created by mixing other colors but they are the main colors used to be mixed to create other colors such as the secondary colors.

4. Secondary Colors
Secondary colors are what is created when you mix two primary colors together. By looking at this image we know that the secondary colors are purple which is made by mixing what two colors? Red and blue. We also see green which is made by mixing which primary colors? Blue and yellow. And lastly we see some orange, which is created by mixing red and yellow together.

5. Tertiary Colors
Think of tertiary colors as the “in between colors.” These colors are created by mixing a primary color with a secondary color. These colors usually don’t have their own special name and are usually named simply after the colors used to create them. For example: When we mix blue and green together we get a color called “Blue-Green” or when we mix blue and violet we get “blue-violet” or “yellow-orange” “yellow-green” “red-orange” etc.

6. Complementary Colors
Complementary colors are the colors that are directly opposite of another color on the color wheel or color chart. These colors are just known as another's complement.
Complementary colors are pairs of colors which, when combined, cancel each other out. This means that when combined, they produce a grey-scale color like white or black.[1] When placed next to each other, they create the strongest contrast for those particular two colors. Due to this striking color clash, the term opposite colors is often considered more appropriate than "complementary colors".
Which pairs of colors are considered complementary depends on the color theory one uses:
Modern color theory uses either the subtractive color model, or the additive color model, and in these, the complementary/opposite pairs are red & cyan, green & magenta, and blue & yellow.
In the traditional RYB color model, the complementary/opposite color pairs are red & green, yellow & violet, and blue & orange, though these pairings fail the modern definition of complementary colors, as they produce a brown color when combined.

7. Monochromatic Colors
Monochromatic colors are all the colors (tints, tones, and shades) of a single hue.
Example of a monochromatic color scheme
Monochromatic color schemes are derived from a single base hue and extended using its shades, tones and tints. Tints are achieved by adding white and shades and tones are achieved by adding a darker color, gray or black.
Monochromatic color schemes provide opportunities in art and visual communications design as they allow for a greater range of contrasting tones that can be used to attract attention, create focus and support legibility.
The use of a monochromatic color provides a strong sense of visual cohesion and can help support communication objectives through the use of connotative color. The relative absence of hue contrast can be offset by variations in tone and the addition of texture.[1]

8. Analogous Colors
Analogous colors are groups of three colors that are next to each other on the color wheel, with one being the dominant color, which tends to be a primary or secondary color, and one on either side of the color. Red, red-orange, and red-violet are examples.
The term analogous refers to having analogy, or corresponding to something in particular. An analogous color scheme creates a rich, monochromatic look.[citation needed] It is best used with either warm or cool colors, creating a look that has a certain temperature as well as proper color harmony. While this is true, the scheme also lacks contrast and is less vibrant than complementary schemes.[cit

9. Cool Colors Vs. Warm Colors
The distinction between 'warm' and 'cool' colors has been important since at least the late 18th century.[1] It is generally not remarked in modern color science or colorimetry in reference to painting, but is still used in design practices today.[citation needed] The contrast, as traced by etymologies in the Oxford English Dictionary, seems related to the observed contrast in landscape light, between the "warm" colors associated with daylight or sunset and the "cool" colors associated with a gray or overcast day. Warm colors are often said to be hues from red through yellow, browns and tans included; cool colors are often said to be the hues from blue green through blue violet, most grays included. There is historical disagreement about the colors that anchor the polarity, but 19th-century sources put the peak contrast between red orange and greenish blue.
Color theory has described perceptual and psychological effects to this contrast. Warm colors are said to advance or appear more active in a painting, while cool colors tend to recede; used in interior design or fashion, warm colors are said to arouse or stimulate the viewer, while cool colors calm and relax. Most of these effects, to the extent they are real, can be attributed to the higher saturation and lighter value of warm pigments in contrast to cool pigments. Thus, brown is a dark, unsaturated warm color that few people think of as visually active or psychologically arousing.
Contrast the traditional warm–cool association of color with the color temperature of a theoretical radiating black body, where the association of color with temperature is reversed. For instance, the hottest stars radiate blue light (i.e., with shorter wavelength and higher frequency) and the coolest radiate red.

10. Grey Scale
Also known as a value scale which shows the light and darkness of colors and also has an impact on a colors intensity.
