Visual perception is a huge topic, much of which is relevant to the work of a designer. I have identified topics in visual memory, visual cognition and colour perception that are relevant, and I'm sure there is more I don't yet know of.
What would be a good place to start for a designer looking for concepts of perception to be aware of when designing? For example, what books (or other accessible resources, such as web pages, applied research topics) exist that are suitable?
I'm very interested in learning more about visual perception and how it pertains to graphic design. I work predominately in print and environmental graphic design but any area of graphic design should be equally applicable.
