# Orphism (オルフィスム)

> An abstraction that returned colour and movement to Cubist fragmentation, painting light itself through rings of simultaneous contrast. Rotating discs and a refracted spectrum generate time and vibration within a static surface. One of the first practices to translate the theory of simultaneous colour contrast into form.

- IndexStyle No.461 — https://indexstyle.org/styles/orphism
- Kind: Style · Family: Geometric Abstraction · Era: 1912–1914
- Mood: Exhilaration, Technology
- Color cues: #e9e6dd / #67635d / #171615 (cues taken from reference works, not a fixed palette)

## Defining characteristics

- Concentric circles and rotating discs
- Hues arranged in spectral order
- Divisions made by intersecting arcs
- Simultaneous contrast of colour

## Best used for

- Motion identities and loading animations built from spinning colour wheels
- Festival and music graphics that turn sound into chromatic rhythm

## Research method

This entry records a historical style; derive the treatment from its sources rather than a fixed recipe:

- Rounded geometric sans, set sparingly so the circles carry the rhythm
- Concentric and interlocking discs sliced by arcs, radiating from off-centre pivots
- Full-spectrum prismatic hues in flat, evenly saturated segments

## What to avoid

Avoid letting the discs decay into generic rainbow ornament; the arcs must follow simultaneous-contrast logic, each hue chosen against its neighbour.

## Application checklist

Before calling a piece an application of this style, check it against the defining characteristics:

- [ ] Concentric circles and rotating discs
- [ ] Hues arranged in spectral order
- [ ] Divisions made by intersecting arcs
- [ ] Simultaneous contrast of colour
- [ ] At least one reference work below has been studied directly
- [ ] The caution above ("What to avoid") has been addressed

- **Cubism (キュビスム)** — A pictorial revolution that freed the subject from a single viewpoint, reassembling facets seen from multiple angles on one flat plane. The fractured planes and muted palette of the Analytic phase, then the newspaper collage and lettering of the Synthetic phase, gave twentieth-century graphic design its founding premise: the picture is not a window onto reality but a field of construction. → https://indexstyle.org/styles/cubism

## 日本語

キュビスムの分解に色彩と運動を戻し、同時対比する円環で光そのものを描いた抽象。回転するディスクと分光したスペクトルが、静止画面の中に時間と振動を生む。色の同時対比理論を造形へ翻訳した最初の実践のひとつ。

特徴: 同心円と回転するディスク／スペクトル順に並ぶ色相／円弧の交差による分割／色の同時対比
