Main Content

The main concepts of Da Cor A Cor Inexistente

In this section, we will summarize some of the main concepts that Pedrosa explains in his book.

Color theory and perception

Pedrosa starts by defining color as a sensation produced by light waves that reach our eyes and are interpreted by our brain. He then introduces the basic elements of color theory: hue (the name of the color), value (the lightness or darkness of the color), saturation (the intensity or purity of the color), temperature (the warmth or coolness of the color), tone (the mixture of hue and value), tint (the mixture of hue and white), shade (the mixture of hue and black), chroma (the difference between a pure hue and a gray), luminance (the amount of light emitted or reflected by a color), brightness (the perceived luminance of a color), contrast (the difference between two colors), complementarity (the opposite colors on the color wheel), analogy (the similar colors on the color wheel), triad (the three colors equidistant on the color wheel), tetrad (the four colors formed by two pairs of complementary colors), monochrome (the use of one hue with different values or saturations), achromatic (the use of black, white, and gray), polychrome (the use of many colors).

Pedrosa also explains how we perceive colors depending on various factors: light source (natural or artificial), illumination (direct or diffuse), background (light or dark), distance (near or far), size (large or small), shape (simple or complex), texture (smooth or rough), transparency (opaque or translucent), movement (static or dynamic), time (day or night), mood (happy or sad), memory (familiar or unfamiliar), association (symbolic or emotional).

Color harmony and contrast

Pedrosa then discusses how to create harmonious and contrasting color combinations that produce different effects: balance (equilibrium between colors), unity (coherence between colors), variety (diversity between colors), rhythm (repetition or alternation between colors), emphasis (focus on one or more colors), proportion (relation between the sizes or quantities of colors), dominance (prevalence of one color over others), subordination (reduction of importance of one color over others). He also presents different types of contrast based on value
