Internal Color

The internal color may also be uniform or variable. Generally it is white or light brown, though some clones display pink to red coloration, seldom uniformly distributed. In some instances the coloration is localized around the eyes (Pas ko, 1973).

Instruments of this type may also be used quite effectively to evaluate kinetics of time-dependent changes in foods, be they enzymatic or reactive changes of other types. The computerized data-acquisition capabilities of these instruments allow precise measurement of absorbance or fluorescence changes, often over very brief time periods ( milliseconds). This is particularly useful for analysis of fluorescence decay rates, and in measurement of enzymatic activity in situ. A number of enzyme substrates is available commercially which, although non-fluorescent initially, release fluorescent reaction products after hydrolysis by appropriate enzymes. This kinetic approach is a relatively underused capability of computerized microspectrophotometers, but one which has considerable capability for comparing activities in individual cells or cellular components. Fluorescein diacetate, for example, is a non-fluorescent compound which releases intensely fluorescent fluorescein on hydrolysis. This product is readily quantified in individual cells which have high levels of esterase [50]. Changes in surface or internal color of foods may also be evaluated over time by these methods. 

Wide Web. In order to achieve accurate color reproduction on different systems, a color profile (International Color Consortium 2003) of the generating system has to be attached to every image. However, the associated color profile of the system that was used, when the image was created, is not always stored with the image. Also, sometimes it may be more convenient not to save this information if the this profile can be inferred in some way.

Precious opal is usually defined by the background color, black, white, or fire (orange). There are terms used to describe the distribution of the internal colors, and which colors are dominant. 

An efficient internal color-conversion technique will only occur if the polymers in the blend are only weakly phase separated. Otherwise, the various polymers in the blend behave similar to independent parallel diodes and hence a strongly voltage-dependent emission color will be observed.131,137... 

The internal color conversion in the m-LPPP PPDB blend can also be used to realize a stable white EL emission, which could be applied to realize a multicolor display according to the method in Sec. 8.2 or it could be used as backlight (e.g., for LCDs).137 140...
