Emission and Control of Colors
Colors can be generated by selective emission, by selective absorption, transmission or by selective reflection.
| Color emission and control | |
|---|---|
| additive mixing primary colors add up to produce white light |
subtractive mixing filters, dyes, pigments (e.g.printing) subtract (absorb) parts of white light |
| temporal mixing (additive) e.g. rotating primary color filter wheel in projectors |
spatial mixing (additive) closely spaced sub-pixels |
| spatio temporal color mixing combined spatial and temporal mixing |
|
| arrangement of sub-pixels for additive color mixing see sub-pixel arrangements 1 see sub-pixel arrangements 2 see sub-pixel arrangements 3 |
subtractive color mixing does not require special sub-pixel arrangements all components (e.g. filters) have to be in the same path of light. |
| Examples: stripe delta-nabla PenTile arrangement, e.g. RGB+White |

Famous quotes containing the words emission, control and/or colors:
“Approximately 80% of our air pollution stems from hydrocarbons released by vegetation, so let’s not go overboard in setting and enforcing tough emission standards from man-made sources.”
—Ronald Reagan (b. 1911)
“We long for our father. We wear his clothes, and actually try to fill his shoes. . . . We hang on to him, begging him to teach us how to do whatever is masculine, to throw balls or be in the woods or go see where he works. . . . We want our fathers to protect us from coming too completely under the control of our mothers. . . . We want to be seen with Dad, hanging out with men and doing men things.”
—Frank Pittman (20th century)
“Thought maps existence; fantasy colors it.”
—Mason Cooley (b. 1927)
