Color saturated

ColorFilm. Most color photographic images reproduced on press are made from positive color transparencies known as sHdes. Transparencies are preferred over color prints for reproduction because of superior sharpness, tonal contrast, and color saturation (see Color photography). 

Preproduction dye developer negatives used a combination of cellulose acetate and cellulose acetate hydrogen phthalate as barrier layers. The images produced from these negatives were outstanding in color isolation, color saturation, and overall color balance. However, solvent coating was requited with this composition, and it was not used in production. 

The salts of Na, Ba and Sr, used as oxidants and to impart appropriate flame colors, are w soluble. Excessive moisture content (over 0.5%) is deleterious in terms of light intensity, color saturation and burning duration. BlkPdr, a widely used ignition source and flame transfer agent, absorbs moisture and deteriorates rapidly. Many instances of pyrot no-fire incidents have been found to be the result of such deterioration (Refs 10,18,21 38)... 

Keeping the solution basic prevents the extraction into the tetralin of acidic products which are highly colored saturating the solution with sodium chloride makes the extraction more rapid. 

Intensity, or chroma, refers to the saturation of a color. A color is saturated when it reaches its maximum intensity. An artist lessens the intensity of a color by adding gray to dull it or by adding the complementary color on the color wheel. The artist is changing the concentration of colored particles in a solution. A chemist knows that a solution is saturated when no more solute can dissolve in a particular volume of a solvent. The chemist expresses solution concentration in a quantitative way. One way for a chemist to express the concentration of a saturated solution is grams of solute per 100 ml of solution. Another way to express the concentration is in moles of solute per liter of solution. In a colored saturated solution, the color is at maximum intensity. If the solution is not saturated, the color is less intense because there are fewer colored particles to bring to the eye the wavelengths that are colored.

Pour a small pile (approximately the size of a dime) of potassium ferricyanide crystals into a small white plastic container. Add about 90.0ml of water, then a splash of plain hypo. The splash will vary based on desired contrast of the mixture. The hypo acts as a catalyst, but ultimately neutralizes the bleach. A solution strong in ferricyanide and low in hypo is fairly contrasty. One lower in ferricyanide and higher in hypo is lower in contrast and slower acting. With experience, you will be able to judge bleach strength by its color saturation. 

The easiest part of the color-matching process is blending the various colors and additives to make the match. The selected colorants and additives should (1) match the hue of the target (watching for metamerism), (2) match the color saturation (chroma value), (3) match the lightness/darkness value, and (4) match the desired level of transparency or opacity. The colorist should consider and allow for the effect of any required additives on the color and evaluate the finished formulation for cost. 

PVC is used in pyrots as a chlorine donor for improved color saturation in flare, signal and tracer formulations (Refs 1,2,3,4, 5,9 11)... 

Equal Euclidean distances in the CIE-Yxy system are not necessarily perceived by a human observer as equal color distances. To match Euclidean and perceived distances, a wide variety of so-called uniform color spaces has been developed (Hunter and Harold, 1987). One of the first of these uniform systems was developed in the early 1900 s by the artist A.H. Munsell. Starting with the observation that brighter hues like yellow and red create a much stronger color sensation at color saturation than darker hues like blue or green, he mounted color chips on a rotating Maxwell disk to... 

At intermediate pressures and temperatures, sulfur changes its color. Saturated vapor between 350° and 500°C is deep red. At 1-10 torr and 500°-650°C, it is yellow-orange. This is caused by an absorption system between 360-440 nm consisting of progressions of vibrational bands and a continuum between 480-600 nm.
