The six layers of visual design
I think you can divide visual design into these layers. Each layer builds on the previous layer but visual design doesn’t always happen in this order.
Content
Textual and visual elements that deliver the message of the interface.
Layout
Layout is the spatial structure/relationships of interface elements.
Typography
The style of text content, including typefaces, spacing, and typographic scales.
Colour
Colours in the interface. In this case shades of grey are colours.
Polish
This layer includes elements and techniques that are not necessary to “complete” a design, but that are used to change how it looks. Usually these efforts are supposed to do one of the following:
- Add visual interest
- Improve visibility
- Separate content
- Connect content
- Guide attention
- Reinforce visual hierarchy
- Reinforce layout
- Reinforce brand
- Reinforce a theme
- Soften the interface
- Signify affordance
- Signify state
- Simulate reality
Animation and other visual changes
Animation is movement of elements. Visual changes include e.g. a field that is highlighted when focused.
