See what happens when you mix together the three primary colors of light: red, green and blue.
Materials
Black garbage bag
Three plastic cups
Three plastic pipettes
Red glow stick
Green glow stick
Blue glow stick
Scissors
Plastic apron and / or gloves (optional)
Directions
Before beginning the activity, let students know that the glow-stick solution they are working with is safe, but they should still keep it away from their eyes, clothes and hands. This activity works best in a darkened room.
Cover your work area with a black garbage bag.
Cut open the end of each glow stick and pour each colored solution into its own cup.
Use a pipette to take small amounts of each color and create new color combinations on the garbage bag. Because there is only a small amount of glow-stick solution, use one drop at a time to mix colors.
What happens when you mix red and blue, or red and green, or green and blue? What happens when you mix all three colors together?
What's happening?
If you look inside a computer or TV screen, you'll see they contain only three colors of light: red, green and blue. The three specific cone cells in our eyes work together, allowing us to translate these three colors of light into millions of different colors.
When red and blue light are combined, the result is magenta. When green and blue light are combined, they make cyan.Red and green light make yellow. And when all three primary colors of light are combined, we see white light.
Red, green, and blue are known as the primary colors of light. The combinations of two of the three primary colors of light produce the secondary colors
secondary colors
A secondary color is a color made by mixing two primary colors of a given color model in even proportions. Combining two secondary colors in the same manner produces a tertiary color. Secondary colors are special in traditional color theory, but have no special meaning in color science.
The light that we see — visible light — falls somewhere in the middle of this "electromagnetic spectrum." All the colors we see are combinations of red, green, and blue light. Visible light may be a tiny part of the electromagnetic spectrum, but there are still many variations of wavelengths.
The colors of visible light, often referred to as ROY G BIV (for red, orange, yellow, green, blue, indigo, and violet), are a small portion of the entire electromagnetic spectrum. Light can be thought of as a stream of packets of energy called photons.
The three primary colours are red, Yellow, and blue because they are the only colours that cannot be made by mixing any other colours. They can be combined to create additional colours which are called secondary colours.
Red, green, and blue are known as the primary colors of light. The combinations of two of the three primary colors of light produce the secondary colors of light. The secondary colors of light are cyan, magenta, and yellow.
What is Tri-Colour? Tri-colour, also known as CCT refers to light fittings where users can switch between warm white, cool white and daylight colour temperatures.
The three-color process aims to reproduce all colors in three printings, by using inks of red, yellow, and blue. Chrome-Gelatine is a perfected modification of the three-color printing process.
The complementary primary–secondary combinations are red–cyan, green–magenta, and blue–yellow. In the RGB color model, the light of two complementary colors, such as red and cyan, combined at full intensity, will make white light, since two complementary colors contain light with the full range of the spectrum.
Your brain interprets the various energies of visible light as different colors, ranging from red to violet. Red has the lowest energy and violet the highest.
In the literature relating to traditional color theory and RYB color, red, yellow, and blue are often referred to as primary colors and represent exemplar hues rather than specific hues that are more pure, unique, or proprietary variants of these hues.
The three primary colors are red, yellow and blue. In traditional color theory these are the 3 colors that cannot be formed by mixing any combinations or other colors. All other colors are derived from mixing these three colors.
As we mentioned above, the human eye has three types of cones that allow us to see a certain range of light and, therefore, colour, on the electromagnetic spectrum – i.e. the visible light spectrum. These colours are blue, green, and red. But obviously, we see much more than just these three colours.
It's almost always white, but often it's tinged with another color around the edges. The three most common colors, aside from white, are blue, yellow, and violet.
"My best advice whatever you're doing, whatever you want to achieve, is to create three layers of lighting—ambient, task and accent," says Patricia Rizzo of the Lighting Research Center. Too many people make the mistake of expecting one type of lighting to do it all. Each type meets a particular need.
This is most prevalent on cyclorama lighting where you traditionally have floodlights in red, green and blue (or a different combination of colors) and you use these to mix the different colors on the back cloth. LED fixtures also use additive color mixing – typically based on the RGB color model.
