Group of Seven vs Hudson River School
グループ・オブ・セヴン / ハドソン・リヴァー派
Both sit in Landscape Painting, so the question is not what they belong to but how they behave. They are reached for with some of the same intent, which is where they get confused.
Group of Seven

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.
Hudson River School

A nineteenth-century American landscape language that joined mountains, rivers, and forests to national grandeur, spirituality, and expansion through immense distance, precise detail, and theatrical light.
| Group of Seven | Hudson River School | |
|---|---|---|
| Era | 1920–1933 | 1820s–1870s |
| Family | Landscape Painting | Landscape Painting |
| Kind | Style | Style |
| Cues | 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 | Vast distance framed by dark trees or rock / Golden light breaking onto a valley or water / Tiny people or buildings against immense nature / Precise vegetation, geology, and atmospheric depth |
| Best used for | Organizing lake, rock, and forest into strong color and contour · Examining national landscape imagery through both its attraction and its exclusions | Making geographic scale and light the protagonists of an environmental exhibition · Placing human activity at a small scale so a campaign can carry deep time and distance |
| Type | Use a concise serif for place and season without bending letters along the landscape. | Set place names and distances in a fine restrained serif. |
| Composition | Weight one side with a foreground tree, then stack lake, island, mountain, and cloud in depth. | Frame the sides with dark foreground, lead through water in the middle distance, and open into a luminous sky. |
| Material | Place thick blue-green, violet, and orange oil paint as clear masses, prioritizing rock and canopy over detail. | Glaze deep greens and browns, reserving transparent blue-grey and gold for the far distance. |
| Caution | 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. | Do not present a sublime empty wilderness while erasing Indigenous land and the politics of expansion. Keep the composition more dramatic and narrative than Luminism. |
