How We See Colour

Humans are trichromats. This means we have three distinct cones which sense different wavelengths and intensities of light.

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

I spy with my little eye...

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?

Colour Blindness

more common protanopia (red cones missing) and deuteranopia (green cones missing) which effect approximately 7% of all males.

Applying Meaning

We also use colour to imply or add meaning. Be careful to pay attention to what colours mean.

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

What kind of meaning do these gradients provide us with?

Drop Shadows

They can make things visually confusiong when inconsistently applied.

Subtle treatments

Often subtle treatments of gradients and drop-shadows can be used effectively to connote depth without confusing the viewer.

Design Issues

Identify what were the problems, and in particular why they were in fact problems. This should guide your P04 process and reworking.

P04 "Significant" Development

We are expecting projects to significantly rework the existing spread given the issues you identify. At the end of the project we will compare and contrast what was done, with the original. Keep this in mind while working on the project.
