Researchers use daylight as the benchmark to which to compare color rendering of electric lights. In 1948, daylight was described as the ideal source of illumination for good color rendering because "it (daylight) displays (1) a great variety of colors, (2) makes it easy to distinguish slight shades of color, and (3) the colors of objects around us obviously look natural".

Physical descriptions of color can be additive (describes mixing of light, RGB) or subtractive (describes mixing of pigment or removal of light, CMYK). Descriptions based on human perception are based on some experimental results on humans. Some models and their variants are employed in parts of the color spaces listed below. [1]
Color quality scale (CQS) is a color rendering score – a quantitative measure of the ability of a light source to reproduce colors of illuminated objects. Developed by researchers at NIST [1] the metric aims to overcome some of the issues inherent in the widely used color rendering index (CIE Ra, 1974). [2] [3]
Welcome to Bloxburg is a life-simulation and role-playing game created in 2014. [116] Based on The Sims, it was noted that it costed 25 Robux to access the game, before becoming free-to-play on June 15, 2024. [‡ 13] [117] It was acquired by Embracer Group in 2023 under Coffee Stain Gothenburg, [b] a subsidiary of Coffee Stain Studio created ...
Radioluminescent paint is a self-luminous paint that consists of a small amount of a radioactive isotope (radionuclide) mixed with a radioluminescent phosphor chemical. The radioisotope continually decays, emitting radiation particles which strike molecules of the phosphor, exciting them to emit visible light.
Without lighting models, replicating lighting effects as they occur in the natural world would require more processing power than is practical for computer graphics. [14] This lighting, or illumination model's purpose is to compute the color of every pixel or the amount of light reflected for different surfaces in the scene. [15]
This is in contrast to other popular methods of lighting such as vertex lighting, which calculates illumination at each vertex of a 3D model and then interpolates the resulting values over the model's faces to calculate the final per-pixel color values. Per-pixel lighting is commonly used with techniques, such as blending, alpha blending, alpha ...
