HUE OR COLOR
The first attribute of color is hue, wich is the name for a color,
such as yellow, green, blue, red.
The color wheel is to represent the basic colors (hues) of the visible spectrum.
All the hues indicated on the color wheel are of full intesity.
For the sake of simplicity, the most common color wheel is made up of 12 color
gradiations, even though there are actually an infinite number of color
gradiations possible between each color on the weel.
VALUE OR LIGHTNESS
The second attribute of color is value, or the relative
lightness or darkness of a color.
Lightness values are archieved by adding white to a color,
and darker values result from adding black.
CHROMA OR SATURATION
The third attirbute of color is chroma or saturation, the relative
purity or intensity of a color determined by how much or how little gray
is added to the color.The value of the color on a chroma scale do not change;
only the intencity of the color varies
So,the three attributes of color- hue, value, and chroma - are what defines every color.Every color as having three dimencions;therefore, to fully describe any color it is necessary to describe each of these dimensions or attributes.
