Projector white balance describes how evenly red, green and blue are combined to reproduce neutral whites and grays across the image. This guide explains RGB balance, grayscale tracking and color temperature, how white balance differs from color gamut and gamma, and why calibration, projector mode, screen conditions and multi-projector matching all influence perceived color neutrality.

Multi-projector color matching helps adjacent projected images appear more consistent in brightness, white balance, and color. This guide explains why identical projector models may still need calibration, how brightness and color differences affect edge blending, why black levels and screen uniformity matter, and how to build a more consistent multi-projector image for immersive projection, simulation, museums, projection mapping and large venue installations.
