## What does light color depend on?

wavelength
The colour of visible light depends on its wavelength. These wavelengths range from 700 nm at the red end of the spectrum to 400 nm at the violet end. Visible light waves are the only electromagnetic waves we can see. We see these waves as the colours of the rainbow.

## What involves the mixing of colored lights?

Additive and Subtractive Color Subtractive Color involves the mixing of colored paints, pigments, inks and dyes.

What is light mixing?

If you mix red, green, and blue light, you get white light. Red, green, and blue (RGB) are referred to as the primary colors of light. Mixing the colors generates new colors, as shown on the color wheel or circle on the right. This is additive color.

### What happens when you mix light?

The Primary Colors of Light Mix all three together and black will result. But the primary colors of light are the secondary colors of pigment, which are red, green and violet.

### What is mixing of colors?

Additive color mixing is creating a new color by a process that adds one set of wavelengths to another set of wavelengths. Additive color mixing is what happens when lights of different wavelengths are mixed. Subtractive color mixing occurs when we mix paints, dyes, or pigments.

When green and red light is mixed?

yellow
When the red and green lights mix, the result is yellow. When green and blue lights mix, the result is a cyan. When the blue and red lights mix, the result is magenta.

## What is the result of mixing all Colours?

Unlike mixing paint, which will give you a darker color, when you mix all the colors of light, you get white light! It happens all the time. When all three colors overlap, they blend to make white. See what happens when you mix different colors.

## What characteristic of light determines the color of a photon?

The color of a photon is determined by the wavelength of the emission. Photons are quanta of light, meaning they are a specific unit of emitted energy…

What do you need to know about mixing light?

Mixing Light delivers you on-going sparks of color grading ideas. As your color grading skills grow, we grow with you. Just a few nuggets a month make a huge difference in your career. We teach interface, theory, technique, business.

### How do you mix light to make colors?

Attach one colored filter over each flashlight, so that you have one red, one green, and one blue light. In a darkened room, project each light onto the wall separately and observe the color. Now choose two of the lights, for example red and green, and project them onto the wall so that their spots of light overlap.

### How are the different colors of light produced?

The production of various colors of light by the mixing of the three primary colors of light is known as color addition. The color addition principles discussed on this page can be used to make predictions of the colors that would result when different colored lights are mixed.

What happens when red, green and blue light are mixed?

When red, green and blue light are mixed or added together with the proper intensity, white (W) light is obtained. This is often represented by the equation below: In fact, the mixing together (or addition) of two or three of these three primary colors of light with varying degrees of intensity can produce a wide range of other colors.
