FarbCRT

FarbCRT is an open-source software project designed to emulate the behavior of analog cathode-ray tube (CRT) monitors, particularly focusing on color reproduction and display characteristics. The project aims to provide a more accurate and visually pleasing rendering of colors compared to standard digital displays, which often lack the warm, analog feel associated with traditional CRTs.

Developed primarily for Linux-based systems, FarbCRT leverages the capabilities of modern graphics drivers to simulate the color response, gamma correction, and phosphor decay effects of vintage CRT monitors. It is particularly popular among retro computing enthusiasts, gamers, and those seeking a nostalgic visual experience. The software can be used with various emulators, such as MAME, DOSBox, and ScummVM, to enhance the appearance of older games and applications.

FarbCRT operates by adjusting the color output of the display through software-based calibration. It applies customizable color profiles that mimic the behavior of specific CRT models, including variations in red, green, and blue phosphor decay rates. Users can fine-tune settings such as gamma, contrast, and color balance to achieve a preferred look. The project also includes tools for generating and editing these profiles, allowing for personalized adjustments.

While FarbCRT is primarily intended for Linux, its principles have inspired similar tools for other operating systems. It is distributed under an open-source license, enabling community contributions and modifications. The project continues to evolve, with updates focusing on improved compatibility, performance, and additional customization options.
