Forest Index is not a single green. It is a scale, moving from deep understory to leafy mid tones and pale botanical paper. That makes it much more flexible than a typical eco palette. It can feel natural, but also archival, academic, and precise.
The darker greens should be used for grounding. The middle greens carry the botanical character. The pale tones make the system usable for content-heavy pages and reports. In gradients, the palette works best when several greens repeat across the canvas instead of forming one simple dark-to-light slope.
How to use it
Use Forest Index for pages that need trust without corporate blue. Let the deep green frame the page and use the lighter tones as a reading field. In slides, it is especially strong for diagrams, research narratives, and nature-adjacent brands.
Color story
The palette feels like a herbarium drawer: preserved leaves, paper labels, shaded glass, and careful observation. It brings nature into design without relying on obvious outdoors imagery.
