How Warm Autumn differs from its neighbours
The three seasons whose reference points sit closest to Warm Autumn in this tool's warm-cool, light-deep, soft-clear space:
- Soft Autumn (compare): chroma (C*) differs most, Warm Autumn is more saturated by 31.8 units.
- Deep Autumn (compare): chroma (C*) differs most, Warm Autumn is more saturated by 17.6 units.
- Warm Spring (compare): lightness (L*) differs most, Warm Autumn is deeper by 18.8 units.

How the numbers are computed
- Each swatch's hex value is converted from sRGB to linear light, then to CIE XYZ under D65, then to CIELAB (L*, a*, b*).
- Average lightness is the mean L* of the six swatches (0 is black, 100 is white).
- Average chroma is the mean C* = sqrt(a*² + b*²) of the six swatches. Higher means more saturated.
- Warmth is the mean b* of the swatches: positive is toward yellow, negative toward blue. The hue angle h° is the angle of the mean (a*, b*) point.
- ΔE*ab (CIE76) is the straight-line distance between the two palettes' mean (L*, a*, b*) points.
These numbers describe TNAADO's illustrative swatches, not skin, hair or any person. Other sites draw the same season names with different colours, so their numbers would differ.

How is Warm Autumn different from Soft Autumn?
The biggest separator is chroma (C*): Warm Autumn is more saturated than Soft Autumn by 31.8 units. Next is warmth (b*): Warm Autumn is warmer by 25.2 units. The full side-by-side is on the compare page.
Is Warm Autumn also called something else?
Some sources call it True Autumn. Naming varies between stylists, so check which palette a source means.
Do I have to wear only Warm Autumn colours if I am Warm Autumn?
No. A season is a style-guide suggestion, not a rule. Colours near your face matter most, so a shade outside the palette is easier to wear as trousers, shoes or a bag. Taste, occasion and what you own count for more than a label.
How do I find out if I am Warm Autumn?
Hold swatches from the palette near your face in daylight, ideally next to a neighbouring season's palette, and see which looks healthier. This page cannot confirm a season; the system is a style tradition, not a measured fact.
What this is, and what it is not
This is a popular style guide, not a scientific test. No peer-reviewed research validates the 12-season system, and results vary with lighting, screens and the system used. The palettes are our own illustrative hex values and will look different on different displays. Use them as a prompt to try colours in daylight, not as a rule.
