- Subtractive color explains the theory of mixing paints, dyes, inks, and natural colorants to create colors which absorb some wavelengths of light and reflect others. The color that an object appears t. Used . o have is based on what parts of the electromagnetic spectrum are reflected by it, or conversely by what parts of the spectrum are not absorbed.
Anything that is not additive col. Used . or is subtractive color. No other color mixing systems are known, except the imperfect system resulting from mixing real pigments, something that is very confusing nowadays.

- A type of discharge lamp with high output generally used in Strobe lights and flashes, though sometimes found in some followspots. These lamps utilize an internal electrical discharge passed between . Used . electrodes suspended in xenon gas. Xenon lamps have a color temperature of between 5600 - 6500°K and produce extremely intense, incoherent, full-spectrum white light usually for very short d. Used . urations. ...Arc Lamp
- An arc lamp is a device that produces light by the sparking (or arcing, from voltaic arc or electric arc) of a high current between two carbon rod electrodes. The rods are touched and then slowly draw. Used . n apart; as the rods separate the current is "struck" and arcs across the gap in a bright, ionized path. The arc produces a temperature of several thousand degrees, and the tips of the carbon. Used . rods are heated to incandescence, creating light. The rods are slowly vaporized during the process and need to be regularly adjusted to maintain the arc. The concept was first demonstrated by Sir Humphry Davy...Beamage

- A high powered light source produced by an arcing electrical discharge between two electrodes suspended in a glass tube filled with gas, usually high or low pressure sodium gas, xenon, mercury vapor, .
