Shape vs. Color

"The brain acknowledges and remembers shapes first. [...] Color is the second in the sequence. [...] The brain takes more time to process language, so content is third in the sequence behind shape and color."
- Alina Wheeler, "Designing Brand Identity"
"Angela Wright, a colour psychologist at agency Colour Affects, adds: 'Colour is noticed by the brain before shape or wording.' [...] The mind absorbs colour before design or wording and it is estimated that as much as 90% of the information taken in about a new brand is related to colour."
- Ruth Mortimer, "The Colour of Money"
So which do we process first, shape or color?
