Now: In Colour
Lecture outline
Starting to work with the complexities of colour in design. Lecture slides will be made available on the day of the lecture (Oct 23).
How We See Colour
Humans are trichromats. This means we have three distinct cones which sense different wavelengths and intensities of light.
Gamut
The gamut describes the colours of the visible spectrum that are available.
Additive vs. Subtractive
Different ways of rendering colour
Additive colour (RGB)
Subtractive colour (CMYK)
Talking About Colour
- Hue: The name of the colour
- Saturation: How intense is the colour
- Lightness: The lightness or darkness.

- Complementary: Colours opposite one another
- Triadic: Colours evenly spaced 3-ways

Why Harmonize?
Colour harmonies allow you to easily build visual relationships. Remember that not all colours are meant to be dominant in a harmony; you should focus on a key colour, and let the others highlight or support.
Applying Colour

How is colour being used in this room?
Meaning of Colour
Colour can help to provide both cultural and informational meaning to a viewer.
Informational Colour
We frequently use colour to convey information, which can run into problems on occassion.
While resolving some of the colour-dependency issues of a light standard, why might the 'uni-signal' have other concerns?

Applying Meaning
We also use colour to imply or add meaning. Be careful to pay attention to what colours mean.
Why meaning matters
How is meaning being applied to suggest 'cultural' meaning?
Colour Interactions
Beware when colour interactions go bad.
Overthinking Meaning
By making this slide blue, I have not magically calmed you all down and made you think of freedom.
Gradients
Gradients
What kind of meaning do these gradients provide us with?
Drop Shadows
They can make things visually confusing when inconsistently applied.
Subtle treatments
Often subtle treatments of gradients and drop-shadows can be used effectively to connote depth without confusing the viewer.
