	Color Grading in After Effects: Basic Color Control
		A very important stage in finishing a project on film or video is color grading or color correction (both terms are used for the same process).
		Nowadays, even material that was shot on film is often transferred to a digital format to allow for digital color grading, which allows for much more interactivity between the image and the colorist, and the possibilities are near endless, as long as the image quality allows.
		All four shots suffer from a yellowish color cast, caused by the fluorescent lighting.

		Remember, color grades are a range and at one point a high H is equal to a low G color.
		Color grades D, E and F are colorless and it is very difficult to see the differences between these because by definition they are colorless.

		Below is a Diamond Color Master Grading Set showing the full color range, from a D all the way to a Z. You would never need a color grading set that goes this far, but this is an striking example of how extreme the range can be.
		Grade "D" is reserved for larger diamonds whose colors can be more accurately graded due to their size.
		The lower colors "M" through "Z" have an increasing amount of yellow tint, ranging through the off colors and ending at the end of the scale, beyond which diamonds are considered to have a fancy yellow color.

	Adiamor - Diamond Color
		Diamond color is one of the most important factors to consider, as it is noticeable to the "naked" eye.
		A diamond's color is graded by GIA on an alphabetical scale from D-Z, with D being absolutely colorless and Z being light yellow.
		Diamonds with a K-Z color grade usually have yellow shading that can be detected by the naked eye, however, a well cut stone with good proportions will still release the brilliance and fire of a lower colored diamond, dispersing light in such a way so as to create a beautiful stone.

	color
		The color grade of a diamond is determined by arranging the GIA master color comparison diamonds about one half inch apart, the lightest on the left and the others on the right in order of increasing darkness To accurately determine color, a diamond must be completely free of all dirt and oil.
		A diamonds color is best observed when viewed through the pavilion in the table-down position on a flat white diamond grading trough with line of sight parallel to the girdle plane.
		A diamonds color grade is determined by moving it along the row of masters comparison guide diamonds until one seems to match.

	GIA: Splendor of Diamonds: Grading Fancy-Colored Diamonds
		Color grading fancy-colored diamonds is a complex process of assessing the color of a diamond in three dimensions: hue (the aspect that gives the color its name - like red, green, or blue), tone (the lightness to darkness of the color) and saturation (the strength or purity of the color).
		Then, after the diamond color is determined, specific terms ranging from Faint to Fancy Vivid are used to describe the combined affect of tone and saturation on that color.
		The grading is an assessment of the "presence of color".

		Color variations are a result of the natural forces (i.e., temperature, pressure, trace elements) at work during the formation of diamonds within the Earth.
		Because subtle color variations dramatically affect the value of a diamond, a color grading scale is used to categorize the shading differences from one diamond to the next.
		Diamonds are graded according to the GIA (Gemological Institute of America) color chart.

	Jewelry Insurance Issues - November 2005: Grading the Color of Colored Diamonds
		For fancy colored diamonds — the fairly small proportion of all diamonds on the market that are naturally colored with dramatic hues, such as pink, yellow, blue or green — assigning a color grade is more complex.
		Unless the grade is based on a system that is widely followed and understood, and one that is standardized to produce repeatable results, the color grade is meaningless.
		For a color grade to be useful, the appraiser must follow a generally accepted system with a nomenclature that is understood.

		The color of graded diamonds is compared to the color of control stones - pre-selected gems of a specific color.
		Colors are therefore graded under controlled lighting conditions and are compared to a master set for accuracy.
		Graded diamonds must also therefore be loose stones, as the color of mounted stones can be affected by their mountings.

		The key to its attractive color is not merely the gemstones simple two-dimensional color, but the balance of light and dark tones in a mosaic-like pattern that gives the gem a wonderful three dimensional appearance.
		Three criteria, attractive color, brilliance, and transparency were used by the GIT to select eight sets of standard rubies weighing from 0.75 to 1 carats from four diiferent geographic regions.
		The color grading of a ruby becomes complicated because we must consider three separate components that are both independent and interrelated, namely hue, tone, and saturation (color intensity).

		When the current grading system was introduced in the 1930’s, diamonds were commonly called grade A, B, or C. So the current system began color grading with the letter D, to avoid any confusion.
		The colors from K to Z are tinted, (usually yellow or yellowish brown.) Those that are just lightly tinted, K, L and M are often said to “set white.” That means that they are so lightly tinted that they will appear white if set in yellow gold.
		Color grading is done by placing a diamond next to a set of previously graded gems.

		Color is personal: some people like a diamond with an ice-cold whiteness (colorless or near-colorless), while others prefer the golden glow of a warmer color.

	Diamond Grading Laboratory Survey
		In two thirds of cases EGL USA color grading was one grade softer but clarity grading in a third of cases was stricter than GIA.
		The reason for a grading lab to give softer grades is to get more business from diamond manufacturers, retailers or wholesalers who want to increase their profits by selling diamonds given higher grades at higher prices.
		This was illustrated by the fact that none of the 17 stones were given the same grade for both color and clarity by all 3 labs.

		In fact, I even RSS a 20% color grade range uncertainty into the numerical computed uncertainty to account for the fact that no machine could “perfectly” reproduce the somewhat imperfect human grading (time of day, shape of body, state of mind).
		The SAS2000 is a high resolution system which utilizes GIA/GTL graded diamond master stones for its color grading calibration and a numerical grading system (0-10) consistent with the AGS colorimeter scale reading, based on the 1950's Shipley Colorimeter.
