Color – Enhancing the composition “Most powerful tool in the designer tool box” Light Theory Visual perception of all color is derived from and is dependent on light Light is a very narrow portion of the electromagnetic radiation spectrum that is visible to the human eye Ergo, if the light is dim, you cannot perceive do the color very well White light is actually the combination of all wavelengths of light Seeing Color We see color in either a reflected form or from a light emitting source Reflected colors are those colors we perceive as inherent to an object o The pigment in an object will reflect its own color and absorb all others o This is why we can’t explain what color is to a blind person who has never seen a color before Colored light is light comprised of only specific wavelengths of light Color Terminology Hue – the quality that differentiates one color from another. The name of the color (red, blue, green, etc) Saturation – the amount or purity of a particular hue in a color mixture Value – relative lightness or darkness of a hue Tint – a hue with a high value. Usually achieved by mixing a hue with white pigment or white light Shade – a hue with a low value. Usually achieved by mixing a hue with one or more hues and/or black Tone – mixture of a hue with black and white. Can be achieved by adding a complementary hue Saturation Hue Color Mixing Primary colors – hues that correspond more or less to the cones in our eyes. Combining all three primaries create black in pigment and white in light o Pigment: red, blue, yellow o Light: red, blue, green Secondary colors – hues that are the result of mixing two primary colors together. o Pigment: purple, green, and orange o Light: yellow, magenta, and cyan Complementary colors – colors that are opposite each other on a color wheel. o Pigment: when combined create black o Light: when combined create white light o *Incorrect that you cannot combine secondary colors More theory than practically based due to purities and impurities Light Color Wheel Pigment Color Wheel Warm and Cool Wheel Color in Pigment Seeing color in paint is primarily a subtractive process Pigments and dyes of specific hues reflect the wavelengths of light that correspond to that hue and absorb all others Color in Light Emitted color consists only of the wavelengths of light corresponding to a certain color o A red LED emits only light with the wavelength which corresponds with red Filtered Light o As white light passes through a filtering medium (glass, plastic, even air), a certain portion of the spectrum is absorbed o The filter material absorbs certain wavelengths of the light and let’s others pass through. The absorbed wavelengths of light is transformed into heat. Color Mixing in Light Subtractive Mixing o Placing colored filters in front of light filters out all hues except for the hue of the filter o Placing more than one filter in front of one source Additive Mixing o When several hues are transmitted to the eye, added together and interpreted by the brain Application in Theatre Pigments used in paints and dyes for use on scenery, costumes, and props o Paint chips and fabric swatches Colored filters such as glass, and plastic placed in front of light to change the color o Plastic filters are referred to as gel Color is a very powerful tool of the scenic, lighting, and costume designers o Use of colors together in overall schemes and accents Meaning of Colors Each person interprets color differently. Their background, age, personality, mood all shape their experience. Color Schemes Monochromatic – variations in lightness and saturation of a single color. Simple, elegant Analogous – colors that are adjacent to each other on the color wheel. One hue is dominant while the second is used to enrich the scheme. Complementary – two colors that are opposite each other on the color wheel. Intrinsically high-contrast Split Complementary – a color and the two colors adjacent to its complementary. High contrast without the strong tension of the complementary scheme. Triadic – three colors equally spaced around the color wheel. Offers strong visual contrast while training harmony and color richness Tetradic – uses two complementary color pairs. The scheme is hard to harmonize if all four hues are used in equal amounts
