# Rayonism (レイヨニスム)

> A Russian abstraction that declared its subject to be not objects themselves but the crossing of light rays reflected from them. Sharp diagonal bundles of lines intersect, dissolving the object into an interference pattern of light. It marked the point where Russian abstraction broke away from Cubism.

- IndexStyle No.462 — https://indexstyle.org/styles/rayonism
- Kind: Style · Family: Russian Avant-garde · Era: 1912–1914
- Mood: Technology, Exhilaration, Calm
- Color cues: #e9e6dd / #67635d / #171615 (cues taken from reference works, not a fixed palette)

## Defining characteristics

- Sharp bundles of diagonal lines
- Planes formed where lines intersect
- Disappearance of the object's contour
- Layering of a restricted palette

## Best used for

- Kinetic-feeling key visuals for events themed on light, sound or speed
- Abstract backgrounds that dissolve a product photograph into radiating lines

## Research method

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

- Sharp, angular display type set on the diagonal, almost absorbed into the ray structure
- Diagonal shafts of line crossing at acute angles; planes appear only at the intersections
- A restricted palette layered in translucent slashes over a dark or neutral ground

## What to avoid

Avoid drawing the object and adding rays on top; if contours survive beneath the lines, the dissolution into pure light fails.

## Application checklist

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

- [ ] Sharp bundles of diagonal lines
- [ ] Planes formed where lines intersect
- [ ] Disappearance of the object's contour
- [ ] Layering of a restricted palette
- [ ] At least one reference work below has been studied directly
- [ ] The caution above ("What to avoid") has been addressed

## 日本語

物体そのものではなく、物体から反射する光線の交差を描くと宣言したロシアの抽象。斜めに走る鋭い線束が交わり、対象は光の干渉パターンへ解体される。ロシア抽象がキュビスムから独立する分岐点になった。

特徴: 斜行する鋭い線束／線の交差でできる面／対象の輪郭の消失／限定色の重ね
