ColorVeil adds a filter of any color and opacity over your Desktop, Internet browser, video player, document, website, or program. Use a red screen for excitement, a blue screen for relaxation, or a sepia screen for nostalgia. Or any other color, for any reason. Just continue to work, play, read, write, or browse as usual. Oh, and adjust screen color and transparency as you see fit. Reduce your screen brightness, even below its lowest available setting. And reduce eye strain, especially at night.
