  1. Colour notation systems

  2. Colour Notation Colour notation systems began to emerge in 18th century & they provided a means of: • Identifying colour • Standardising colour across different applications from graphic & textile design through to printing, production, manufacture, etc Previously, colour matching was conducted manually (that is, visually) and was therefore open to variation and error

  3. Munsell Colour System Developed in the early 20th century Provides a means of identifying and notating colour as well as a methodology for creating colour combinations and colour harmony. Munsell identified colour using the attributes of hue, value and chroma (saturation) wherein tone occurred in a range of ten values and chroma up to twelve values (Kuehni, 2002). http://munsell.com/

  4. Munsell Colour System A colour can be notated by listing the three numbers for hue, value, and chroma. For example 5G 5/10 5G representing mid green (hue) 5/ meaning medium value (lightness) 10 represents the chroma (saturation level) NOTE: We will discuss Munsell again in future lessons

  5. Pantone Colour Notation System The Pantone system provides a range of products and services that focus on identification of colour in terms of paints, pigments and inks (subtractive colour) (Kuehni & Schwarz, 2008) Launched in 1962, the system allows for colour consistency from design to printers, paint manufacturers, textile dyers, etc Wide range of colour identification products available including the Pantone Matching System http://www.pantone.com/

  6. Pantone Colour Notation System The Pantone system provides translations into CMYK as well as computer colour systems such as sRGB and HSV Photoshop includes a translation device in its Color Picker tool Benefits: colours consistency can be maintained from design to printing or other applications

  7. NCS Colour System The Natural Colour System (NCS) evolved from the research of Ewald Hering whose research focussed on human colour perception (Hard, Sivik & Tonnquist, 1996). The NCS system (subtractive colour reproduction) includes six primary colours: red, green, blue, yellow plus white and black. A proprietary system owned by the Scandinavian Colour Institute AB, NCS offer a large range of colour identification & colour management tools, products & services.

  8. NCS Colour System A colour identified as S 1050-Y90R represents: S Standardised colour (one of 1,950 NCS standard colours) 10 Percentage of blackness (10%) 50 Percentage of “chromaticeness” (50%) – these figures can be deducted from 100 to give a percentage of whiteness: 40% Y Yellow 90 Percentage of colour related to the last letter (R) & therefore 10% yellow R Red (NCS, 2011).

  9. CMYK Not a colour notation system Prior to digital printing technology, the CMYK colour model was commonly used in the printing industry; Key colours are: cyan (C), magenta (M), yellow (Y) and black (K). The CMYK four colour printing process is used to create a wide gamut of colours in the printing industry Ink is applied in the sequence: CMYK (Feisner, 2000; Kuehni & Schwarz, 2008)

  10. CMYK C M Y K CMYK has its limitations & ‘spot’ colour is often required

  11. CIE 1931 XYZ Colour Space Commission Internationale de l’Eclairage (CIE) – an international authority on light, illumination and colour http://www.cie.co.at/ CIE 1931 XYZ colour space was developed to identify & describe visible colour CIE 1931 XYZ model

  12. CIE 1931 XYZ Colour Space An additive colour model, the CIE 1931 XYZ colour space uses three values: x (red), y (green) and z (blue) to identify visible colour Three colour values: X, Y, Z

  13. sRGB Colour Space An additive colour model, the sRGB colour space: based on the CIE colour space (where X, Y & Z represent red, green & blue) Developed by Hewlett Packard and Microsoft. Designed to maintain colour consistency across different types of computers, applications & over the Internet ‘s’ represents ‘Standard’ sRGB colour space

  14. Carmine sRGB (175-15-50) Vermilion sRGB (227-66-52) Indian yellow sRGB (227-168-87) Indigo sRGB (17-80-147) Ultramarine sRGB (18-10-143) Tyrian purple sRGB (102-2-60) sRGB Colour Space Below are some common colours notated in sRGB

  15. sRGB Colour Space The sRGB colour space has a limited gamut of colours. As computer technology evolved, colour consistency across different computers became problematic. Consequently HSL colour space was developed. Providing a greater range of colours The limited gamut of colours in sRGB colour space

  16. HSL, HSB & HSV Colour Spaces The HSL model is used in computer applications and has the three dimensions of hue (H), saturation (S) and luminance (L)

  17. HSL, HSB & HSV Colour Spaces Similarly, the HSB model depicts colour using dimensions: Hue (H) Saturation (S) Brightness (B).

  18. HSV Colour Model The HSV model attempts to reproduce colour using the artist’s notions of hue, tint, shade and tone within the constraints of computer applications. Colour is reproduced using: Hue (H) Saturation (S) – from full chroma to nil chroma Value (V) – levels of blackness or non-blackness – black being zero energy in a computer monitor.
