  2. Colour

  3. colour spectrum The concept of additive colour theory was developed around 1690 by Sir Isaac Newton who discovered that white sunlight passing through a prism split into different wavelengths of light - the colours of the spectrum. Main Menu

  4. Colour Wheel pure colour Hue Main Menu

  5. primary colours Next

  6. primarycolours can be foundequally spaced onthe twelve partcolour wheel primary colours Main Menu

  7. each secondarycolour is a mixture oftwo primary colours secondary colours Main Menu

  8. Complementarycolours can be foundopposite each other onthe twelve partcolour wheel complementary colours Next

  9. complementary coloursprovide maximumvisual contrastof hue complementary colours Next

  10. The sum of any twoprimary colours makesthe complement of theremaining primary complementary colours Main Menu

  11. colours which areclose to each other onthe colour wheel analogous colours Next

  12. colours harmoniseeasily and arepleasing to the eye analogous colours Next

  13. they can include tones,tints and shades analogous colours Main Menu

  14. this complementaryvariation introducesslight variations ofthe contrastingcolour split complementary colours Next

  15. using adjacentcolours to theopposite hue split complementary colours Next

  16. the effectis vibrant and exciting but less harsh thantwo straightcomplementary colours split complementary colours Main Menu

  17. Colour + white hue Hue +white Hue +more white Tints Next

  18. Colour + black hue Hue +black Hue +more black shades Next

  19. hue colour + grey tones Next

  20. hue 70% tint 50% tint 30% tint +light grey +dark grey Main Menu

  21. the same grey, shown as a central square, gives the illusion of being lighter set against a dark tone and darker when set against a light tone simultaneous contrast of tone Next

  22. the same effect occurs when the same grey is set against colours of different value simultaneous contrast Next

  23. The same grey is shown against a different background colour simultaneous contrast of colour Next

  24. look at the central spot after a few seconds the same grey has the illusionof appearing different in colour - taking on a complementary hue of its background colour Next

  25. The same yellow is shown against a different background colour simultaneous contrast of colour Next

  26. look at the central spot after a few seconds the same yellow has the illusionof appearing different in colour - it appears more intense set against a contrasting hue Main Menu

  27. look at the central spot and try to remain fixed on it until the screen changes successive contrast Next

  28. the complementary colour appears as an afterillusion as your eyes adjusted to the loss of colour successive contrast Next

  29. try the illusion againwhat colour will appear? successive contrast Next

  30. purple / mauve Main Menu

  31. primary colours red blue yellow subtractive colour i.e. using colour pigments Next

  32. secondary colours two pigment primaries mixed together create a secondary colour purple orange green subtractive colour Next

  33. secondary colours When mixing paint it is often proves difficult to mix an intense colour hue using the traditional primaries. Some colours appear dull. purple orange green subtractive colour Next

  34. Red and yellow, mixed, create a good orange in this example, but purple and green appear dull secondary colours purple orange green subtractive colour Main Menu

  35. magenta yellow cyan printing primary colours Next

  36. magenta + black yellow cyan to reproduce the widest range of colours printersuse four process colours - magenta, yellow and cyan + black Next

  37. printing primaries printing primaries mixed together create good secondary colours Next

  38. theoretically, all are mixed to create black but in practice this is impossible to achieve Next

  39. thus black is printed as an additional colour to provide definition and depth Main Menu

  40. additive primary colours Next

  41. when all light primaries are mixedwe see white additive colour i.e. using light Main Menu
