INTD 53 coloring agents

all designers must use materials in the creation of their works: achromatic—neutral, such as black, white or grays chromatic—hued, such as red, yellow, or brown

additive color mixing mixing of light colored filters in front of projected light ray—red, blue or green video camera records images transmitted as light patterns chromaticity: measure of the combination of hue and saturation luminance: measure of value (lightness or darkness)

additive color mixing picture tube: coated with dots of phosphors in red, green, and blue activated by transmitted signals resulting in color image computer monitors: much the same way based on munsell system screen image additive (brighter)/printer image subtractive (duller)

subtractive color mixing based on pigments or dyes pigments: powders in a binder such as acrylic or oil which covers or adheres to a surface dyes: pigments that are dissolved and absorbed in a fluid

subtractive color mixing dyeing mordants help fiber accept and fix dye— alum, iron, tannic acid, tin, copper procedures vary natural: from animal & vegetable sources, metals, minerals & clay synthetic: first aniline (alcohol & coal tar) then azo (petroleum-based), more colorfast and brilliant

subtractive color mixing pigment best function: should not react (fade/turn pale) when mixed with light or liquids should have permanence— remain stable in any atmosphere should cover well and retain brilliance

subtractive color mixing binders & grounds: artist must be concerned with behavior of pigment tinting strength— refers to the intensity with which pigment reacts when mixed with white & binder most surfaces/grounds begin with white binders classified as dry or liquid—oils, waxes, gums, water or acrylics

subtractive color mixing color printing: four-color process printing screens of dots layered on top of each other

subtractive color mixing color printing: PMS system (pantone matching system) based on nine colors, plus black and transparent white “recipes” create different colors

subtractive color mixing photography: works in black-and-white or color

participation activity: off-white samples …using the cardstock handout and the variety of hues available, create a variety of “whites" white one drop variation
