#637e1d - Birch Leaf Green color

A muted, earthy olive — deep grass green tinged with warm yellow and mossy brown undertones. It reads as a vintage military or botanical hue, evoking late-summer fields, damp forest floors, and sunlit foliage. Calm and grounded, it pairs beautifully with creamy neutrals, rich browns, navy, or warm metallics like brass. Versatile for interiors, packaging, and nature-inspired branding, it brings a rustic, organic sensibility while still feeling robust and slightly energetic instead of overly dark or somber.
