Orange

red-orange · coral · tangerine · safety orange · amber

Orange opens close to red, expands through flowering coral and fungal peach, then reaches amber and yellow-orange.

Coral orange

Cumberland Azalea

Rhododendron cumberlandense

Apricot-orange flowers deepen to coral along their ruffled, starry edges, with long rust-red stamens reaching well beyond the petals. The loose clusters spill over a layered rock bank among fresh green leaves, gray ledges, and the darker foliage of the woods.

Field fact and source

Cumberland Azalea resembles flame azalea, a similarity that helped obscure its identity for years. E. Lucy Braun formally named the red azalea of the Cumberlands Rhododendron cumberlandense in 1941; its type locality is Yahoo Ridge, Kentucky. Later botanical work notes that it usually blooms two to four weeks after flame azalea, once its leaves have expanded. Virginia Tech taxonomic history →

Peach to warm orange

White-Pored Chicken of the Woods

Laetiporus cincinnatus

Broad salmon-orange shelves stack into rippling rosettes, each fan banded with peach and finished by a narrow cream edge. Close views reveal velvety upper surfaces and a chalk-white pore layer; on the steep wooded bank, light passes through the thinner margins above dark roots, stone, and moss.

Field fact and source

White-Pored Chicken of the Woods can fruit from buried hardwood roots, which is why a broad orange rosette may appear to rise directly from the forest floor. Its cool cream-white underside separates it visually from yellow-pored relatives. USDA Forest Service study →

Red-orange

Red Chanterelle

Cantharellus cinnabarinus

A tiny cinnabar-red chanterelle lifts a curled, irregular cap above a short orange stalk. Apricot ridges appear beneath the folded edge, while gravel, splintered sticks, gray stones, and dark soil make the small flare of color easy to measure.

July · Research Grade

Field fact and source

The cinnabar color comes from pigments within the fruiting body: this chanterelle contains a mixture of carotenoids, with canthaxanthin as a major component. Beneath the cap, color continues across blunt, branching ridges rather than thin blade-like gills. Published pigment study → Michigan State University Bonito Lab →

Tangerine

Common Jewelweed

Impatiens capensis

The blossom hangs like a small tangerine pouch, freckled with brick-red spots and tapering into a delicate curved spur. A butter-gold hood folds over the opening, while thin succulent stems and broad blue-green leaves soften the shaded lakeshore around it.

Field fact and source

A ripe Jewelweed seedpod behaves like a wound spring: a light touch makes its five sections curl back suddenly and fling the seeds. That small burst of stored motion explains the other common name, Touch-Me-Not. University of Minnesota Extension →

Brilliant orange

Eastern Newt

Notophthalmus viridescens

This saturated orange eft is the Eastern Newt’s terrestrial teenager—a juvenile stage spent walking the forest floor before returning to water as an adult. Its curling tail, black-ringed spots, pebbled skin, tiny feet, and narrow toes stand out against cream, rust, and blue-gray creek stones.

Research Grade

Field fact and source

Eastern Newts change palettes as they change habitats. Aquatic larvae are yellowish green; terrestrial juveniles range from reddish brown to brilliant red-orange; and aquatic adults become olive green, dark green, or yellow-brown above with a yellowish belly. The eft's conspicuous orange accompanies toxin-bearing skin and warns potential predators. Red spotting also varies among the four recognized subspecies. U.S. Geological Survey →

Orange to yellow

Orange-Gilled Waxcap

Humidicutis marginata

A glossy tangerine-orange cap arches above closely spaced gills of the same saturated hue. The slender stalk fades toward lemon yellow, and a fingertip beside the mushroom sets its delicate size against curled brown leaves and damp soil.

Amber to yellow-orange

Orange Jelly Spot

Dacrymyces chrysospermus

Marigold-orange folds gather on rain-darkened bark like small translucent ruffles. Their glossy, gelatinous surfaces catch the light at close range, while the wider view reduces them to brilliant pinpoints on a slender charcoal-brown trunk.

Field fact and source

Orange Jelly Spot is a wood-decaying fungus of dead conifer wood. Its gelatinous fruiting bodies can emerge in merging groups during wet weather, which is when their color becomes hardest to miss. Orange Jelly Spot profile →

Tawny orange · pearl silver

Great Spangled Fritillary

Argynnis cybele

Folded wings carry large pearl-silver windows across cinnamon brown and tawny orange. With each turn, the upper wings open into brighter orange panes divided by black lines, while dusty pink flower clusters and broad green leaves place the butterfly among its late-summer colors.
