- Brightness is a setting found on monitors. Unlike contrast (which should be set to its maximum setting in most cases), brightness should be set manually according to your profile software's instructions. As the phosphors in your monitor fade over time, the amount of light they emit will decrease and you will probably have to turn your brightness up. If you are unable to turn it up to an acceptable level it's time for a new monitor. Give yours to your favorite accountant - they'll love the size and not care about the color.
- B component in HSB; the visual attribute by which a color appears to exhibit more or less light. This correlates directly with the amplitude of the light waveform (as opposed to the purity or the wavelength(s))
