Color definition

For the Spectra film, the blue-light sensitive sandwich has been radically altered by the utilization of thiazolidmc dye release. This required the creation of new molecules and a new dye-release mechanism involving only a minute quantity of silver. By utilizing this hybrid imaging system, chemical interaction and molecular cross talk between the red-, green-, and blue-sensitive sandwiches have been reduced, which results in greater color definition. 

These definitions have arisen from popular usage, so there is little wonder that they overlap. What one person might call smog someone else could call haze, and both would be correct. Therefore we should generally use the more precise, if less colorful, definition of aerosol and then fill in the details on a more qualitative basis. 

Among polyphenolic compounds, two types of flavonoids, the anthocyanins and flavanols (i.e., catechins, proanthocyanidins, condensed tannins), are particularly relevant to the quality of red wines, as they are key compounds for color definition and astringency. Other flavonoids such as flavonols may have some influence on color and bitterness, although they are present in red wines in much lower amounts. Phenolic acids and hydrolysable tannins, released from barrel wood, may also have an influence on wine taste and color, and hydroxycinnamoyl derivatives from grape must are involved in the oxidative browning of white wines together with flavanols. Besides, some of these perceptions may be modified by other sensory characteristics (e.g. sourness, sweetness) related to other wine components (Preys et al. 2006).
