Adding colors, Layering, Mixing, and Producing New Colors
How Does Natural Light and the Three Primary Colors Produce the Mixture of Colors?
How Different Shades and Pigments are Added to Paints
How Does Adding Light Affect the Subtraction of Color?
Mixing Colors
Light and optics are involved in many aspects of art and painting. Dyes are substances that are also used to color objects. Only saturated compounds show color. A scale of complementary In modern day, almost any color imaginable can be found with using a medium of oil, egg yolk, or acrylic.

Primary Colors of Color
The primary colors of light are red, blue, and yellow. There are three basic categories of color that are useful: the color wheel, color harmony, and how colors are used.
Primary Colors of Light
The primary colors of light are red, blue, and green. Any of the primary colors of light from all colors can be obtained by additive color mixing.
When you look at an object, is the color really what you see or are your eyes tricking you?

Is adding light really possible when it comes to color? Of course!

How is Natural Light Used to Develop Paint Colors?
Just like there are primary colors and light, there are also primary paint colors.
Our sensitive eyes perceive specific colors on the electromagnetic spectrum through rods and cones. These colors consist of: red, orange, yellow, green, blue, indigo, and violet.

The electromagnetic spectrum consist of a wide variety of things we can see, to things that are harmful and we can not see, such as gamma rays.

When one looks at an object, the eyes and brain work together to perceive light. An object gives off every color except the color one's eye absorbs.

The Electromagnetic Spectrum
and Visible Light
Primary Colors
Color and Vision
While one may think colors appear with different shades and pigments, colors, in fact, contain different wavelengths in which the human eye corresponds to.
Each color represents a specific and sensitive "range" and wavelength throughout/involving light. Each wavelength also contains small particles known as photons.

Light does not have color, however, when it is reflected, absorbed, or emitted of an object, our eyes perceive the color that, that object does not absorb.

Light is thought upon as the appearance of an object. It is classified by diffraction, refraction, and reflection. However, light always moves in a straight line.
"Color can be thought of as a physiological and psychological response to light waves of a specific frequency or set of frequencies impinging on the eye."
There are three primary colors that make up the base of all colors: red, blue, and yellow.
These three colors are mixed, added, and subtracted to achieve different pigments and shades.

Red, green, and blue (primary colors of light) are cones used in wavelengths: red cones, blue cones, and green cones.

When three primary colors are added together, they can ultimately perceive/ and be made into white.
The red, blue, and green cones "produce impulses: that are sent along nerves throughout the eye and the brain. This production is signaled and stated when a photochemical reactions occur. For example, when a wheel that contains the three primary colors on it (red,blue, and green) is spun, our eye can not distinctly perceive eye color, and instead absorbs the wheel as either white or brown.
Light Waves Involve Refraction, Diffraction, and Reflection
Light waves involve refraction, diffraction, and reflection as a way of the eye perceiving a color.

Light first enters the eye through a layer called the retina, this is near the pupil. When the light enters the retina, rods, cones, and nerve impulses within the brain stem work together to produce and perceive color and light.
Reflection is the process of light "bouncing off" one object/obstacle/block from one area of space to another. Reflection involves a "point of incident" to indicate the direction of a reflection.
Diffraction is simply the direction and changes that waves undergo when an obstacle/object is present in it's space.
All of these light waves, wavelengths, and natural light work with one's eye to both perceive light, and observe how light is absorbed, refracted, and reflected.

The three primary paint colors are known as cyan (c), magenta (m), and yellow.

These three colors are used to develop a desired color or "effect."

Each primary paint color is "matched" with a subtraction of the primary colors, red, blue, or yellow.

The ultimate factor in a colors appearance is determined by subtraction and complementary colors involving light and color that are "given."
Magenta

Magenta, being one of the primary paints colors, absorbs the primary color: green. There is a specific amount of light and color absorption that matches magenta with the green light reflection.
Cyan
The next primary color is cyan (c). Cyan paint absorbs the primary color red. Primary and secondary colors are found in the darkness of shades and pigments involving absorption.
Primary Colors of Paint
Primary colors of paint and primary colors are often confused to be the same, however they are not only different, they also work together to produce pigments and dies.

One primary color of paint is used to absorb one primary color. These colors are able to produce complementary colors by working together.

To understand how paints and dyes are produced, one must understand that these paints and dyes must demand and have the ability to absorb "specific components."
Background of Subtraction of Color--What is it?
The subtraction of color is basically modified light perceived as color. The subtraction of color is mostly demonstrated as chemical dyes, such as dyes found in clothing, food coloring, etc.

-White light is a combination of different wavelengths
Demonstration of the Mixing of Colors
In the image to the left, the three primary colors(yellow, red, and blue) are used first to begin the process of mixing different colors to make the secondary colors (green, orange and violet).
Adding light is the base of how we develop different pigments, shades, mixes of color, and even white. Adding shades begins with the base of the three primary colors. Using these colors, we can determine frequency, subtraction of color, and complementary pigments.
Adding colors involves mixing, layering, and adding the three primary colors on top of one another to produce other, new colors.
New colors produced by overlapping are called secondary colors.
In order to produce a specialized and specific appearance, colors will subtract light to produce a pigment. A distinct and special process goes into what is known as "the process of color subtraction."
Isaac Newton was the first man who experimented with light and the light spectrum. He observed paint wheels, dotted paints, and prism light reflections. He observed the following:

The amount of frequency relies on the amount of intensity. And likewise, the amount of intensity, allows depends on the frequencies.

The special term "primary colors of light," is used to describe any and all three frequencies and intensities that ultimately come together to form white light.

White light is important because it involves the absorption of all the other colors.

How Is Natural Light Perceived by the Eye?


Refraction occurs when the path of light bends, particularly between two mediums. Refractions are often seen to distort and/ or change an object.
Shade and pigments are added to paints using different tints. The tints increase lightness, which helps to create lighter colors such as cyan. Shades are a mixture of a color and black.

Primary colors are sets of colors that can be combined to make a range of colors. The primary colors of color are red,blue, and yellow and the primary colors of light are red, blue, and green.
