Warm, rich skin tones (True Autumn)

Where this season sits

True Autumn is fixed by three things and nothing else: it is warm-toned, deep in value and clear. Undertone decides which half of the wheel is yours, value decides how dark the colours run, and chroma decides how much grey sits in them.

Metals follow the undertone, which is why gold is the one to wear. The four neutrals below are the ones to build on, because a wardrobe is mostly neutrals and only occasionally a colour.

• #6B5842: deep, nearest common name olive green (ΔE 14.1).
• #8F7A5C: mid-tone, nearest common name camel (ΔE 13.5).
• #C4B394: light, a beige (ΔE 5.2).
• #3E3226: very deep, a chocolate brown (ΔE 8.6).

Colours that work on True Autumn

These are the colours from an ordinary shop rail that land inside the True Autumn palette. The number after each is the distance from the colour to the closest thing in the palette: under 12 reads as the same colour family, and everything here is measured rather than judged.

• Rust (#B7410E): ΔE 5.0 from #B5541E.
• Beige (#D9C6A8): ΔE 5.2 from #C4B394, one of the season neutrals.
• Olive green (#6B6B3A): ΔE 5.4 from #5C6B2C.
• Teal (#1F7A78): ΔE 6.9 from #2F6B60.
• Mustard (#D4A017): ΔE 7.6 from #C4903C.
• Camel (#C19A6B): ΔE 7.7 from #C4903C.
• Terracotta (#C36A4E): ΔE 8.4 from #A85838.
• Chocolate brown (#4A2C1A): ΔE 8.6 from #3E3226, one of the season neutrals.

Colours to leave on the rail

These sit far enough from the palette that they read as borrowed from someone else's colouring. Black, blush pink, sky blue and lavender are worse than merely distant: they land on the season's own avoid list, which is the short list of colours that actively work against this colouring.

• Navy (#1B2A4A): ΔE 22.9 from #3E3226, one of the season neutrals.
• Mauve (#9A7B8C): ΔE 23.2 from #8F7A5C, one of the season neutrals.
• Blush pink (#E8BFC4): ΔE 21.2 from #C4B394, one of the season neutrals.
• Fuchsia (#D6218C): ΔE 30.3 from #A04428.
• Cobalt blue (#0047AB): ΔE 33.7 from #2F6B60.
• Sky blue (#8FC1E3): ΔE 30.3 from #C4B394, one of the season neutrals.
• Lavender (#B9A5D6): ΔE 32.2 from #C4B394, one of the season neutrals.

The seasons either side

Palettes overlap. Deep Autumn and Soft Autumn are the closest to True Autumn measured across every colour in both, so if the season label ever feels one notch off, those are where to look first.

This matters more than it sounds. A twelve-season label is a convention imposed on a continuous space, and the honest reading of a borderline result is not a different label but a smaller claim.
