Color Lookup Table in Computer Graphics: What It Is and How to Download It
How to Use Color Lookup Table in Computer Graphics: A PDF Guide
Color lookup table (CLUT) is a technique that is widely used in computer graphics to store and manipulate color values efficiently. A CLUT is a table that contains a set of predefined colors, each associated with an index or a code. A CLUT can be used to map pixel values in a frame buffer to actual colors on a display device, or to perform various color transformations and effects on an image. In this article, we will explain what a CLUT is, how it works, and how to download a PDF guide that will teach you how to use CLUT in computer graphics.

What is a CLUT and how does it work?
A CLUT is a data structure that stores a finite number of colors, usually in the form of RGB (red, green, blue) values. Each color in the table has a unique index or code, which can be used to access or modify the color. A CLUT can have different sizes and formats, depending on the number of bits used to represent each color and each index. For example, a CLUT with 8 bits per index and 24 bits per color can store up to 256 colors, each with 16 million possible shades.
A CLUT can be used for various purposes in computer graphics, such as:
Color mapping: A CLUT can be used to map pixel values in a frame buffer to actual colors on a display device. For example, if a frame buffer has 8 bits per pixel, each pixel can reference any one of the 256 positions in the CLUT, and each position can store an RGB color value. This way, the frame buffer can display up to 256 different colors at once, while using only 8 bits per pixel. This reduces the memory and bandwidth requirements of the frame buffer, and allows for faster rendering and display.
Color transformation: A CLUT can be used to perform various color transformations on an image, such as changing the brightness, contrast, hue, saturation, or gamma of the image. For example, if we want to increase the brightness of an image by 10%, we can simply add 10% to each color value in the CLUT. This way, we do not need to modify each pixel value in the frame buffer individually, which would be slower and more complex.
Color effect: A CLUT can be used to create various color effects on an image, such as dithering, halftoning, posterization, or false color. For example, if we want to create a dithering effect on an image, we can use a CLUT that contains only two colors: black and white. Then, we can assign each pixel value in the frame buffer to either black or white based on some algorithm or pattern. This way, we can create an illusion of gray levels or shades using only two colors.
