3. Intensity : Intensity is the brightness or dullness of a hue (color). Pure hues are high-intensity colors.
Brightness refers to intensity, distinguished by the amount of shading mixed with the hue . Any desired hue of light can be produced when various amounts of two of the primary colors of light—the primary colors being red, green, and blue—are combined mechanically, either by addition or by subtraction.
Value refers to the lightness or darkness of a color. A light color is a tint. For example, pink is a tint of red. A dark color is called a shade.
Hue defines pure color in terms of “green”, “red” or “magenta”. ... Hues are basic colors we learn to connect with words as children. Hues can refer to the set of “pure” colors within a color space.
In color theory, colors are organized on a color wheel and grouped into 3 categories: primary colors, secondary colors and tertiary colors .
Luminosity is the rate at which a star radiates energy into space . Apparent brightness is the rate at which a star’s radiated energy reaches an observer on Earth.
Opposite of the quality or state of being bright or illuminated . dullness . blackness . dark . darkness .
As far as I know, brightness is defined in optics as a component of color. Therefore it depends not only on the intensity of the light, but on our perception of it. It is more closely related to luminous intensity than to radiant intensity.
The properties of color are hue, saturation, brightness and temperature .

– The color wheel is a tool used to visually display the laws of color. Haircolorists use the color wheel to formulate haircolor by selecting complementary or enhancing colors. The three primary colors are blue, red and yellow . All other colors are made from a combination of these colors.”
Luminance : Although brightness is often used interchangably with luminance, we prefer to use the term “lightness.” This concept deals with many of the same variables as value but using a different mathematical equation.
Black and white create the highest contrast possible.
RGB means Red Green Blue , ie the primary colors in additive color synthesis. A RGB file consists in composite layers of Red, Gree and Blue, each being coded on 256 levels from 0 to 255. For example, black corresponds to the levels R=0, G=0, B=0, and white corresponds to the levels R=255, G=255, B=255.
