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.

Colour matters

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


Colour matters

the same effect occurs when the same grey

is set against colours of different value

simultaneous contrast

Next


Colour matters

The same grey is shown against a different background colour

simultaneous contrast

of colour

Next


Colour matters

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


Colour matters

The same yellow is shown against a different background colour

simultaneous contrast

of colour

Next


Colour matters

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


Colour matters

look at the central spot and try to remain fixed on it until the screen changes

successive contrast

Next


Colour matters

the complementary colour appears as an afterillusion as your eyes adjusted to the loss of colour

secondary colours

two pigment primaries mixed together create a secondary colour

Colour matters

secondary colours

When mixing paint it is often proves difficult to mix an intense

colour hue using the traditional primaries. Some colours appear dull.

Red and yellow, mixed, create a good orange in this example,

but purple and green appear dull

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

Next


Colour matters

printing primaries

printing primaries mixed together create good secondary colours

Next


Colour matters

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

Next


Colour matters

thus black is printed as an additional colour to provide definition and depth
