Hello friends! This time I want to share about the color of light. What color is that light? And why is RGB the color of light? Come on, let’s see the explanation!
The color of light is the color produced by a light source, such as the sun, stars, fire or lamp. The color of light is different from the color of pigment, which is produced by objects that absorb and reflect light. Pigment colors usually use the CMYK (Cyan, Magenta, Yellow, Black) color model, while light colors use the RGB (Red, Green, Blue) color model.
RGB stands for Red (Red), Green (Green), and Blue (Blue). These three colors are called additive primary colors, which are colors that can be mixed to produce other colors.
For example, if we mix red and green, we get yellow. If we mix red and blue, we get magenta. If we mix green and blue, we get cyan. And if we mix all three at the same intensity, we will get white.
RGB is the color of light because the three are different spectrums of light.
Light itself has different spectra, such as the rainbow that forms when white light is reflected by a prism. Using a prism, we can see that white light is actually made up of different light spectrums that have different wavelengths and frequencies. Red is the light spectrum with the longest wavelength and lowest frequency. Blue is the light spectrum with the shortest wavelength and highest frequency. Green is the light spectrum in between.
By using RGB, we can create different colors of light by adding or subtracting the intensity of each primary color. The intensity of a primary color is usually measured on a scale of 0-255, where 0 means no light and 255 means full light. For example, if we want to make the color dark red, we can use the RGB code (128,0,0), which means the intensity of red is 128, green is 0, and blue is 0. If we want to make the color gray, we can uses the RGB code (128,128,128), which means that the intensity of the three primary colors is the same.
So, that’s a brief explanation about light color and RGB. Hopefully useful and add to your insight. See you in the next post!
