Hue Theory in Photography and Color Photography

Before beginning to paint a room, you must be sure of how many shades of color you will need. To be exact, you should have the color number of all the colors which will be used in the painting. Having a general idea about the shade of color needed is much easier and quicker while calculating the paint amounts. The process of matching the color number with the paint color can take a few minutes to complete. The following tips will help you to achieve your desired color match.

Saturating Colors. The first digit of each color number represents the saturation of that color in a particular hue or shade. The hues are further divided into three basic finishes; flat, semi-gloss and gloss. For ease in measuring the color shade to that needed, the hue value should be defined.

Hexadecimal Number System. A hexadecimal number system is an arbitrary code consisting of up to sixteen numbers. Each color code in the color number should be considered separately and their relative intensities should be carefully considered. The color hue for red, orange and yellow should always be considered in linear degrees, while the shades for blue, green and violet should be considered in radians.

Determining the Value of Second Digit. In case you are using two different colors or more than one color in a painting, it becomes necessary to be in a position to determine the value of the second digit of each color. To do so, you may use the CSS color number rules which specify the color values in terms of their relative intensities.

Applying Color Theory to Hues. For practical reasons, it is convenient for artists to not allow the values of the second digit of colors to change over a wide range of hues as that may alter the level of lightness or darkness. In cases where the color values of the second digit change rapidly, such as in hues with a yellow-green contrast, it is better to use the values of the second digit in the place of actual saturation, e.g., a hue value of (100%(red),(yellow) or (white). As an example, (100%(red),(yellow) represents the maximum amount of red that is allowed while (0%(red),(green) represents the minimum amount of yellow that is allowed. If the hue value is based on the saturation of a color, then you can use the formula: (Hues(int color(s) * saturation} hues | color | hue number | color number | different} Applying Color Theory to Colors. To create harmonious color combination, different hue patterns should be considered. The hue pattern can be considered as a separate concept from the appearance of colors. This will allow different hues to be compared against each other. To simplify color combination, the hue number will be derived from the main dominant color in the image, as discussed above.
