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 (February 17).
Sketching together
To help with practicing sketching, let's take another go at today's sketching exercise.
How We See Colour
Humans are trichromats. This means we have three distinct cone cells 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.

Colour Harmonies
Types of harmonies
- Monochromatic: One colour's tint, tone and shade
- Analogous: Colours next to one another
- Complementary: Colours opposite one another
- Triadic: Colours evenly spaced 3-ways
Making Colour Harmonies

Please head to ah.link/palette and make an example of each of the palettes above.
Colour Relationships
Colour Relationships
How does the relationship change our views of the colours?
Colour Contrasts
Contrast of hue.
Contrast of light and dark.
Contrast of saturation.
Colour Contrasts
Contrast of hue.
Contrast of lightness.
Contrast of saturation.
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.

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?

Colour review
Please head to color.review. Use pairs of colours from your palette to find:
- One pair of colours who are too low contrast
- One pair of colours that are sufficiently high contrast
Take a screenshot (WINDOWS+SHIFT+S) and share it with the zoom chat.
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.
Making meaning
Please head back to ah.link/palette and make a palette that you feel conveys a particular cultural meaning.
- Save and share the palette to the chat.
- Describe what you believe the palette conveys.
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.
Open feedback session
Today we are going to use the last part of class to give more open feedback on where folks are at. This is meant to help us learn a bit more from one another rather than within the (terrifying) zoom breakout rooms.
Break time!
Please return for class in 10 minutes
