In older TV sets, the picture tube contained a colored matrix of red, blue and green (primary colors) coating that was applied to the inside of the front of the picture tube. The neck of the tube contained an "electron gun" that emitted a stream of electrons that impacted the coated tube surface. When an electron impinged the surface, it gave off energy, visible as light. The electron beam was controlled by a "deflection" circuit that caused the beam to sweep across the tube horizontally, and also move from top to bottom vertically. The end result is the creation of visible light on the screen. There is more to it, but this gives you an idea. Current TV's use projection circuit, etc., but the basic principle is the same.
What else can I help you with?
Do colors seen on tv screen result from color subtraction or addition?
addition
Colors seen on tv result from color?
They result from color addition, if you look really closely at an old tv you'll see three distinct colors: red, green, blue.
Which color can be seen from far away?
Red is the color that can be seen from far away because its wavelength is big, compared to the other colors.
What is the difference between additive color mixing and subtractive color mixing?
Additive color mixing involves combining different colors of light to create new colors, as seen in electronic displays. Subtractive color mixing involves mixing pigments or dyes to create new colors, as seen in printing and painting.
What is the difference between additive and subtractive color models?
Additive color models involve combining different colors of light to create new colors, as seen in electronic displays. Subtractive color models involve mixing pigments or dyes to absorb certain colors of light and create new colors, as seen in printing.
What color can be seen in the color wheel?
The color wheel consists of primary colors (red, yellow, blue), secondary colors (orange, green, violet), and tertiary colors (a mix of primary and secondary colors). Additional colors can be created by blending these base colors in varying proportions.
What is the difference between additive and subtractive color mixing?
Additive color mixing involves combining different colors of light to create new colors, as seen in devices like TVs and computer screens. Subtractive color mixing involves combining different colors of pigments or dyes to create new colors, as seen in painting and printing.
Is white colour a secondary colour?
No, white is not considered a secondary color. In traditional color theory, secondary colors are created by mixing primary colors. White is often referred to as a neutral color that is seen as the absence of color or the combination of all colors.
What colors can be seen in a spectroviewer?
The colors red, orange, yellow, green, blue and violet can be seen in a spectroviewer. Each color has a height depending on what is being looked at in the spectroviewer.
What is quaternary color?
Quaternary colors are created by mixing two tertiary colors. In the traditional color wheel, tertiary colors are formed by blending a primary color with a secondary color. Therefore, quaternary colors can be seen as the next level of color mixing, resulting in more complex hues. These colors are less commonly referenced in basic color theory but can be useful in advanced color mixing and design.
What is the relationship between light, color, and the spectrum of the color wheel?
Light is made up of different colors that can be seen on the color wheel. The spectrum of the color wheel shows the range of colors that can be created by combining different wavelengths of light. Each color on the color wheel corresponds to a specific wavelength of light, and when these colors are combined, they create new colors.
What color is seen frequently in sumi-e paintings?
warm colors
