The best background color for computer screens can depend on the specific use case and personal preference. For general use, white is a popular choice as it provides accurate colors and bright light, making it ideal for watching movies, TV shows, or presentations in well-lit environments. However, white can also lead to washed-out images in rooms with bright ambient light. Black is another option that can reduce strain on the eyes, especially when using dark text on a light background. Grey is also a popular choice as it can add a subtle sense of depth and sophistication to product images. Ultimately, the best background color for computer screens will depend on the individual's needs and preferences.
