# Feature examples
|
||
|
||
Values below are deterministic outputs from extractor v1. OKLCH tuples are `(L, C, hue°)`; `null`
|
||
hue means chroma below `1e-7`.
|
||
|
||
## KMS8892 — required corpus example with physical dimensions
|
||
|
||
- Source/analytical palette: 7 / 7 colours, uniform weight 1/7.

|
||
colortemp 3.3317.

|
||
- Source visual and geometry are unavailable.
|
||
- Flags include `PALETTE_DUPLICATE_SOURCE_COLOR`, `IMAGE_BUNDLE_INCOMPLETE`,
|
||
`VISUAL_FIELDS_PARTIAL`, and `PHYSICAL_GEOMETRY_MISSING`.
|
||
- It is not added to either corpus feature Parquet.
|
||
|
||
## KMS1571 — near-achromatic
|
||
|
||

|
||
- Chromatic hues cluster around orange/yellow (35.54°–103.59°); black has null hue.
|
||
- Centroid OKLCH: (0.4793, 0.0772, 68.93°).
