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.

Soft Autumn palette FAQ
What colours are in a Soft Autumn palette?
In this tool, Soft Autumn is shown as six illustrative swatches: #B8A27C, #C58F6B, #8E9F78, #A98A7A, #6E8F8A, #D9C7A3. Soft and slightly warm. Muted earthy colours with low contrast. These are TNAADO's own values, and other sources draw Soft Autumn with different colours.
How is Soft Autumn different from Soft Summer?
The biggest separator is warmth (b*): Soft Autumn is warmer than Soft Summer by 20.1 units. Next is chroma (C*): Soft Autumn is more saturated by 8.4 units. The full side-by-side is on the compare page.
Is Soft Autumn also called something else?
The name Soft Autumn is widely used, though some sources use different labels for neighbouring seasons. Naming is not standardised.
Do I have to wear only Soft Autumn colours if I am Soft 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 Soft 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.
