Color characteristic: Hue ACC color system Color characteristic: Hue Hue is the name, such as red, blue or yellow, given to each color to distinguish it from other colors. Hue, the characteristic that gives color its place in the spectrum is best represented in the form of a continuous circle.

Color characteristic: Saturation ACC color system Color characteristic: Saturation Saturation of a color corresponds to its intensity or ‘richness’. The greater the color content, or amount of color pigment it exhibits, the greater the saturation, the stronger the color. Low saturation High saturation

Color characteristics: Lightness ACC color system Color characteristics: Lightness high Lightness All colors vary from light to dark. Lightness tells us how light or dark a color is. The more light reflected the lighter the color is perceived. A light color has a high lightness. low Lightness

ACC color system The color space High lightness Low lightness The color space indicates that every hue has its own range of lightness and saturation Low lightness Low saturation High saturation

C0.50.30 ACC ACC color system Clear color communication The ACC color system offers an easy to handle and accurate color language for easiness in color choice. ACC is a clear and constant tool that can be used to communicate about colors, without actually showing the physical color samples. The ACC system is recognized as a language that professional users of colors understand.

ACC ACC color system Color identification Color identification The ACC codes are a result of scientific measurement and calculation taken human perception into account. Quality is warranted with a short code that identifies all colors in an accessible way by means of color documentation and visualization tools. In short the ACC system enables the customer to identify or specify colors exactly, irrespective the paint product.

Observing colors ACC COLOR SYSTEM Exercise color harmony colored samples colored cubes Exercise color harmony Harmony in color can be realized in two different ways: Harmony by analogy A color will always harmonize with itself and with shades or tints of its own hue. Colors harmonize because they all form part of the same hue. But within that hue, there can be considerable contrast in terms of saturation and tone. Harmony by contrast A contrast implies a large difference - but is not the opposite of harmony. Contrasts can be harmonious or discordant, and the distinction does not necessarily depend on the degree of contrast.: Tools for this exercise color samples include: 8 color samples exercise color harmony and working sheet color harmony. Stick the color samples on the right position as indicated on the working sheet Next fold the working sheet into an 3 dimensional octahedron. - Finally indicate examples of harmony by analogy or harmony by contrast 4 colored cubes having Explanation see working sheet © SK, 2009

ACC color system Explanation exercise: Harmony in color can be realized in two different ways: Harmony by analogy A color will always harmonize with itself and with shades or tints of its own hue. Eg. A0 colors or J0 colors. Harmony by contrast A contrast implies a large difference: Contrast in hue: A0.20.30 versus J0.20.30 A0.20.60 versus J0.20.60 A0.10.60 versus J0.10.60 A0.07.77 versus J0.07.77 Contrast in saturation A0.20.60 versus A0.10.60 or J0.20.60 versus J0.10.60 Contrast in lightness A0.20.30 versus A0.20.60 or J0.20.30 versus J0.20.60 Contrast in hue, saturation and lightness A0.20.30 versus J0.10.60 or A0.10.60 versus J0.20.30 The maximum contrast is achieved when two colors differ by the maximum number of ‘steps’ in hue, saturation and lightness. A0.07.77 versus J0.20.30 or A0.20.30 versus J0.07.77
