värvivõrkude

Värvivõrkude, also known as color netting or color grids, refers to a technique used in digital image processing and computer graphics to represent and manipulate color information. Instead of storing color as a single value, it is broken down into multiple channels or layers, each representing a specific component of the color. The most common color model utilizing this principle is the RGB (Red, Green, Blue) model, where each pixel's color is defined by the intensity of red, green, and blue light.

In this system, an image is essentially composed of three separate grayscale images, one for each primary color. Each of these "color grids" stores the intensity of its respective color across the entire image. When these three grids are superimposed, they combine to form the final, full-color image that humans perceive. Other color models, such as CMYK (Cyan, Magenta, Yellow, Key/Black) used in printing, also employ a similar layered approach.

The concept of värvivõrkude is fundamental to how digital cameras capture images, how displays render them, and how image editing software manipulates color. By separating color into distinct channels, it becomes possible to adjust the intensity of individual color components, leading to effects like color correction, special filters, and the creation of complex color palettes. This layered representation allows for precise control and efficient processing of visual information in the digital realm.
