Hard-Edge Painting
ハードエッジ・ペインティング / 1959–1970s / Style / Geometric Abstraction
Painting that keeps every boundary perfectly sharp and builds the picture out of flat planes of colour alone. Brushwork and gradation are excluded, so the edge of a plane becomes the only event. The precise edge obtained by masking is the direct ancestor of later flat design and vector work.

At a glance
Visual cues
- Perfectly sharp boundaries between planes
- Flat colour with no gradation
- A few large planes only

Dictionary entry
- Type
- One geometric sans, cut to the same edge precision as the colour, with no shadow
- Composition
- Three or so fields, divided off any obvious fraction, the outer shape part of the composition
- Material
- Flat opaque colour, the edge cut mechanically, with no overlap and no halo of light
- Caution
- Feathering even one edge for depth brings back illusionistic space and the work becomes a picture of something, while sharpening edges and multiplying fields builds no tension and leaves a colour coded diagram.
