Cavern Glow
Deep underground warmth — torch-lit stone, iron oxide, and firelight bouncing off cave walls.

Moss & Basalt
Volcanic rock overgrown with life — dark stone, rich greens, and fungal accents. The hobbit hole palette.

Red Clay
Iron-rich earth, terracotta, and the rusty reds of deep sediment layers. Warm and grounded.

Subterranean Blues
Underground rivers, crystal caves, bioluminescent pools. Cool and mysterious with warm mineral accents.

Magma Core
The deepest layer — molten rock, volcanic glass, and the glow of the earth's mantle. Bold and intense.

Cavern Glow — Brown Roots
Cavern Glow accents married to the site's actual brown gradient. Neutrals built from the existing header (#2C2419) and gradient stops, so the background flows seamlessly into header and footer.

Gradient Reference
Torch & Earth
Shifts the primary toward gold/amber — warmer, less punchy than Ember Orange. The browns are extended directly from the gradient into a full neutral scale. Feels like firelight on packed earth.
Primary
Secondary
Neutrals
Ember Underground
Keeps the hot orange but swaps cool teal for warm mineral tones — copper and ochre. The whole palette stays in the warm family so nothing fights the brown gradient. Darker, moodier.
Primary
Secondary
Neutrals
Green phosphor on a CRT in a dark room. Terminal nostalgia with a magenta-black void.
