Warm Autumn (or True Autumn) is the warm, medium-deep, richly coloured centre of the Autumn family. The palette evokes harvest, fired earth, and burnished metal. The twelve hex codes above are the anchor points. The rules below explain why they fit together.
What makes a colour Warm Autumn
Three traits converge.
Strongly warm undertone, dominant trait. Of the three Autumn variants, Warm Autumn is the most decisively warm. Pigments lean yellow, golden, orange, and earthy red. Cool casts (icy blue, true pink, lavender) are excluded entirely.
Medium-to-deep value. The palette sits in the middle-lower part of the lightness scale, between 30 and 60 per cent lightness for most pieces. Lighter than Dark Autumn, deeper than Soft Autumn.
Medium chroma. Saturation is high enough to feel rich and grounded but never electric. Clearer than Soft Autumn, more muted than the Spring family.
Lose the warmth and you slip into Cool Summer or Cool Winter. Lose the medium chroma and you drift toward Soft Autumn (less) or True Spring (more). Lose the medium-deep value and you move toward Dark Autumn or Soft Autumn.
Warm Autumn versus its neighbours
- Soft Autumn is one step softer and lighter. Same warmth, lower chroma, lighter value. If Warm Autumn colours feel too vivid, Soft Autumn is the move.
- Dark Autumn is one step deeper and slightly more chromatic. If Warm Autumn colours feel pale at the deep end, Dark Autumn carries weight better.
- True Spring shares warmth but is brighter and lighter. If clear vivid colour works and earthy tones feel heavy, True Spring is the better season.
The Warm Autumn / True Spring confusion happens because both are decisively warm. The drape test against pumpkin (Autumn) versus coral (Spring) settles it.
How to use these hex codes
The twelve codes split into four practical groups.
Oranges and reds. Pumpkin #D87838 is the signature. Burnt orange #C25030 is the deeper saturated orange. Rust #B85838 is the everyday red-orange. Tomato #D04828 is the mid red. Warm red #B83828 and Brick #983828 cover the darker end.
Yellows and metallics. Mustard yellow #D8A028 is the wardrobe yellow. Bronze #A87038 is the metallic anchor. Warm gold #C09040 is the lighter metallic.
Greens. Olive green #707838 is the everyday green, ranging from yellow-green to grey-green depending on the piece. Forest green #386838 is the deeper green.
Neutrals. Chocolate brown #5C3D24 is the darkest neutral, replacing black entirely. Warm cream is implied as the lightest neutral; pair the palette with a warm off-white surface in design work.
Hex math behind the palette
Three programmatic conditions.
-
HSL hue in 0-60 (warm reds, oranges, yellows) and 60-120 with low saturation for warm greens. Pure cool blues, violets, and pinks are excluded.
-
HSL saturation between 35 and 65 per cent. Medium chroma. Below 35 the palette drifts into Soft Autumn; above 65 into True Spring or Bright Winter.
-
HSL lightness between 25 and 60 per cent. Medium-deep value. Anything lighter pulls toward Soft Autumn; anything darker toward Dark Autumn.
The colour finder reports HSL coordinates for any hex.
How to know if you are Warm Autumn
Daylight checks against bare skin.
- Pumpkin, mustard, and burnt orange make your skin glow.
- Pure white blouses look stark; warm cream looks balanced.
- Black ages and drains the face.
- Yellow gold, copper, and bronze jewellery flatters; silver looks cold.
- Veins read green, olive, or warm against the wrist.
- Hair has rich warm tones — copper, auburn, deep golden, chestnut, dark warm brown.
- Eyes are warm — hazel, golden brown, warm green, deep brown with gold flecks.
- Earth tones feel like a natural extension of your own colouring.
If five or more match, Warm Autumn is a confident call. A drape test against Soft Autumn (lighter and softer), Dark Autumn (deeper), and True Spring (brighter and lighter) confirms the season.
Warm Autumn in brand and product work
The palette has natural premium, editorial, and craft-brand quality. It signals warmth, heritage, and grounded values.
Body text on Warm cream surface with Chocolate brown #5C3D24 gives 11.8:1, easily passing WCAG 2.1 AA at any size. Rust #B85838 against warm cream gives 4.7:1, just passing. Pumpkin #D87838 against warm cream gives 2.9:1, suitable for large display but not body text.
The pattern for a Warm Autumn brand is straightforward: warm cream surface, chocolate brown body text, pumpkin or rust accents, and bronze for premium touches like icons or borders. See the colour accessibility article for the underlying luminance maths.
Building a Warm Autumn wardrobe
Five anchors carry the system. A Chocolate brown coat. Cream trousers. A Mustard yellow knit. A Rust blouse. A Forest green dress.
The palette is internally coherent through shared warmth and depth. Every piece coordinates because the underlying three-trait signature is consistent. Add accent pieces in pumpkin, brick, and olive one at a time to expand the wardrobe without breaking the system.
