# Group of Seven (グループ・オブ・セヴン)

> A Canadian group that simplified northern trees, exposed rock, lakes, and clouds into broad contours and non-natural color, enlarging fast outdoor oil sketches into national landscape statements.

- IndexStyle No.703 — https://indexstyle.org/styles/group-of-seven
- Kind: Style · Family: Landscape Painting · Era: 1920–1933
- Mood: Exhilaration, Calm, Nostalgia
- What this family collects: Landscape traditions separated by whether land, weather and light are organized as everyday observation, spiritual sublimity or a national image.

## Brief inputs

Supply these before production. They are intentionally not invented by the style.

- Deliverable and channel: page, app screen, deck, campaign image, garment, object or space
- Subject and message: what the audience must notice or understand first
- Audience and context: where, when and at what viewing distance it will be encountered
- Format: dimensions, aspect ratio, responsive states, slide count or physical constraints
- Content hierarchy: required copy, data, actions, imagery and legal information
- Production constraints: accessibility, materials, budget, image rights and delivery deadline

## Defining characteristics

- Wind-bent trees and exposed rock
- Blue-green, violet, and orange simplified into large shapes
- High viewpoints layering lake, island, and distance
- Small-study brushwork enlarged onto exhibition canvases

## Best used for

- Organizing lake, rock, and forest into strong color and contour
- Examining national landscape imagery through both its attraction and its exclusions

## Composition recipe

- Typography & lettering: Use a concise serif for place and season without bending letters along the landscape.
- Layout & structure: Weight one side with a foreground tree, then stack lake, island, mountain, and cloud in depth.
- Material & texture: Place thick blue-green, violet, and orange oil paint as clear masses, prioritizing rock and canopy over detail.

## Colour

Read off the reference works below, so a direction rather than a fixed palette.

- Ground: #D57B45
- The colour it is remembered by: #6A7547
- Text and outlines: #315E63

## Evidence and rights boundary

- Treat the source of record and reference works below as evidence for understanding the style, not as assets to reproduce.
- The AI interpretation image, when present, is a browsing aid only. It is neither a reference work nor evidence for the definition.
- For a branded design system, translate hierarchy, spacing, colour roles and component logic into an unrelated fictional service. Do not copy logos, proprietary type, icons, product copy, screenshots or exact component geometry.
- For a regional, Indigenous or community-rooted tradition, retain place, authorship and historical context. Do not combine unrelated motifs or reduce the entry to generic ethnic decoration.
- For fashion and subculture, distinguish documentary context from a costume prompt; use fictional adults and avoid real labels, public figures and caricature.
- Record the rights status and intended use of every supplied image, typeface, logo and quotation before production.

## Translate it by medium

The rules below preserve the visual grammar without copying a historical artefact literally.

### Web and app

- Page structure: translate “Weight one side with a foreground tree, then stack lake, island, mountain, and cloud in depth.” into the hero, section rhythm and information hierarchy.
- Type system: use “Use a concise serif for place and season without bending letters along the landscape.” for display moments and short labels. Keep body copy, navigation, forms and status text in a highly legible companion when the display treatment reduces clarity.
- Components and imagery: carry “Place thick blue-green, violet, and orange oil paint as clear masses, prioritizing rock and canopy over detail.” through image treatment, borders, dividers, cards and selected surfaces; do not decorate every component equally.
- Tokens: begin with #D57B45 as the ground, #6A7547 as the memorable colour, and #315E63 for text, outlines and high-contrast detail. Assign colours by semantic role before tuning individual components.
- Presentation: render the screen itself as the design artefact. Add a phone, browser chrome or perspective mockup only when the deliverable explicitly asks for one.
- Responsive behaviour: preserve hierarchy, alignment logic and the dominant cue when columns collapse; do not reproduce a desktop composition by merely shrinking it.
- Usability gate: keyboard focus, action labels, contrast, zoom and reduced-motion behaviour remain explicit even when the historical style did not account for them.

### Slides and decks

- Title slide: express one idea with the strongest scale, alignment or framing move from “Weight one side with a foreground tree, then stack lake, island, mountain, and cloud in depth.”.
- Content slides: keep the reading layer quieter than the title layer. Use one dominant characteristic per slide and repeat the same grid, margins and type roles across the deck.
- Images and surfaces: art-direct crops, masks, rules and backgrounds with “Place thick blue-green, violet, and orange oil paint as clear masses, prioritizing rock and canopy over detail.” rather than adding unrelated decoration.
- Charts and diagrams: use #D57B45 as the ground, #6A7547 as the memorable colour, and #315E63 for text, outlines and high-contrast detail; preserve labels and numerical contrast before stylistic treatment.
- Presentation: deliver a flat slide canvas by default. A photographed screen, laptop or conference room is a different deliverable and must be requested explicitly.
- Sequence: alternate emphatic slides with quiet explanatory slides so the style has rhythm instead of becoming constant noise.

### Image generation and art direction

- Subject: choose one concrete subject that serves one of the uses above; the style is the treatment, not the subject.
- Composition: build the frame from “Weight one side with a foreground tree, then stack lake, island, mountain, and cloud in depth.”. Make the focal hierarchy readable before adding texture.
- Lettering and graphic marks: follow “Use a concise serif for place and season without bending letters along the landscape.”. If text is not essential, omit it; if it is essential, use short neutral wording and reject illegible pseudo-text.
- Surface, light and finish: interpret “Place thick blue-green, violet, and orange oil paint as clear masses, prioritizing rock and canopy over detail.” as material, texture, edge quality, depth and lighting rather than as a generic filter.
- Effect discipline: gradients, bloom, glass, chrome, heavy shadows, grain and distressed paper are off by default unless the material direction names or clearly requires them.
- Cliché test: remove the most obvious period prop or motif. The style should still read through composition, type, colour relation and material behaviour.
- Set direction: make a clear establishing composition, a changed crop or viewpoint, a material/detail study, and a reduced alternate. Keep the visual grammar stable while changing the framing.

### Styling, objects and spaces

- Silhouette and proportion: translate “Weight one side with a foreground tree, then stack lake, island, mountain, and cloud in depth.” into the distribution of volume, balance, symmetry or asymmetry.
- Materials and finish: start from “Place thick blue-green, violet, and orange oil paint as clear masses, prioritizing rock and canopy over detail.”; choose real materials whose behaviour supports the style instead of printing a motif onto an unrelated surface.
- Graphic detail: apply “Use a concise serif for place and season without bending letters along the landscape.” only where lettering, labels, trims or wayfinding have a reason to exist.
- Palette: use #D57B45 as the ground, #6A7547 as the memorable colour, and #315E63 for text, outlines and high-contrast detail. Let one role dominate, one support and one provide legibility or edge definition.
- Edit: carry two or three defining characteristics strongly. Avoid turning every characteristic into a literal prop or costume reference.

## What to avoid

Do not repeat the myth of untouched wilderness. Make Indigenous land and nation-building visible, and simplify contour more strongly than the Hudson River School.

- **Post-Impressionism (ポスト印象主義)** — A collective name for painters who found the improvisation of Impressionism insufficient and recovered structure, symbol and emotion, each in their own way. It is not one style but several answers standing side by side, among them pointillism, flat fields of color and surging brushwork. Twentieth century abstraction branched off from here. → https://indexstyle.org/styles/post-impressionism
