| Joseph W. Lovibond invented a visual colorimeter and a system for colorimetry based on subtractive color mixing. |
| It is a subtractive system that removes the unwanted colors from white light. |
| His subtractive procedure is the ruthless evacuation of everything taken-for-granted as a prelude to the construction of a new Good. |
| This intermodulation creates an effect called heterodyning, where additive and subtractive tones, known as beat frequencies, are created. |
| Mixing two of them produces cyan, magenta and yellow, also called the subtractive colors. |
| A suppressive, subtractive hybridization procedure was applied to dissected midguts of the budworm exposed to sub-lethal levels of the toxin. |
