Flat
Solid fills, crisp edges, no depth cues — flat and direct.
What it is
Flat design removes shadows, gradients and skeuomorphic texture in favour of solid colour blocks and clean typography. It reads fast and scales cleanly across screen sizes.
When to use
Bright, friendly consumer apps and anything that benefits from bold colour and quick scanning.
When not to
Interfaces that rely on realistic depth or subtle elevation to convey layering and focus.
