© UNT in partnership with TEAAAVTC: Advanced AV Production - Color Theory2 Upon completion of this unit, you should be able to explain the additive color theory and describe how it is used in video.

What is Color? © UNT in partnership with TEAAAVTC: Advanced AV Production - Color Theory3 Color : “ The appearance of objects or light sources described in terms of the individual’s perception of them, involving hue, brightness, and saturation.” Webster’s II New College Dictionary

What is Color? © UNT in partnership with TEAAAVTC: Advanced AV Production - Color Theory4 Webster’s I New College Dictionary Hue:Hue: “The dimension of color referred to a scale of perceptions ranging from red through yellow, green, and blue, and circularly back to red.”

What is Color? © UNT in partnership with TEAAAVTC: Advanced AV Production - Color Theory5 Webster’s I New College Dictionary Brightness: “The dimension of color that represents its similarity to one of a series of achromatic colors ranging from very dim to very bright.”

What is Color? © UNT in partnership with TEAAAVTC: Advanced AV Production - Color Theory6 Webster’s I New College Dictionary Saturation:Saturation: “Degree of difference from a grey of the same lightness or brightness: vividness of hue.”

Electronic Color © UNT in partnership with TEAAAVTC: Advanced AV Production - Color Theory11 Electronic color is used in video cameras and displayed on television and computer screens through the use of cathode-ray tubes (CRT).

Electronic Color © UNT in partnership with TEAAAVTC: Advanced AV Production - Color Theory12 Color monitors use three different types of phosphors that appear red, green, and blue when activated. These phosphors are placed close together, and when combined in differing intensities can produce any color.

Electronic Color © UNT in partnership with TEAAAVTC: Advanced AV Production - Color Theory13 Color video cameras use a prism system to split the light into the red, green, and blue signals.

Pigment Based Color © UNT in partnership with TEAAAVTC: Advanced AV Production - Color Theory20 Red Pigment-based color is used in color printers, color filters, and color paints.

Pigment Based Color © UNT in partnership with TEAAAVTC: Advanced AV Production - Color Theory21 Red Color printers use cyan, magenta, and yellow pigments. These pigments when combined in differing intensities can produce any color.
