| Flat Design / Vector Minimalism | Grunge | |
|---|---|---|
| Era | 2010s– | 1990s |
| Family | UI Expression | Counterculture |
| Kind | Style | Style |
| Cues | Uniform planes / Simple shapes / Few shadows / Clear color | Scuffing / Tears / Disordered type / Low-quality copies |
| Best used for | Light, understandable explanation · Large sets of consistent figures | Body heat for music and street culture · Deliberately breaking the look of a finished product |
| Type | A rounded sans-serif | Decayed sans, typewriter faces |
| Composition | Simple silhouettes and clear hierarchy | Overlap and crop; keep alignment only in places |
| Material | Three to five colors; shadows only when they mean something | Dirty paper, grain, low chroma plus one accent |
| Caution | Figures easily become generic. Define your own ratios, lines and color rules. | Texture overlays alone feel dated. Run the logic of wear through photo, type and margin alike. |
