Why Use Red Screen?

• Red light lets you see without ruining your dark adaptation. Astronomers, campers, and pilots use red lighting for exactly this reason.
• Red sets a dramatic tone for photos, videos, or just the vibe in your room.
• Running a pure red screen alongside green and blue helps you check whether individual color channels on your display are working properly.
