Blend Mode Family List Lookup
Supported blend-function family classification, not arbitrary blend syntax or color-space conversion. Explicit supplied computed/layout context only; not a browser cascade/layout engine or cross-browser guarantee.
Description
Blend modes combine source and backdrop under different channel rules.
Blend modes combine source and backdrop under different channel rules.1
A family label does not calculate pixels or perform alpha compositing. Use Blend Mode Family List Lookup to look up a supported term.
When to use Blend Mode Family List Lookup
Use Blend Mode Family List Lookup to look up a supported term. Choose the exact supported token from the table; preserve its punctuation and capitalization.
How to use Blend Mode Family List Lookup and understand its results
- Choose the exact supported token from the table; preserve its punctuation and capitalization.
- Enter Blend mode using the field table and validation rules below, then run the tool.
- Read Meaning and interpret units, signs, ordering and placeholders as explained below.
- If the tool reports an input error, correct that field and rerun. A successful false result, empty match list or unknown-evidence placeholder has the specific meaning described here; check the limitations before applying the result.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| blendMode | Blend mode | string | Required; constraints below |
Enter one of the exact supported blendMode tokens in the table below. The implementation performs a case-sensitive lookup and returns the stored meaning without interpreting a stylesheet, audio recording or performance. Unsupported tokens, added whitespace and alternate capitalization are input errors. The entries describe a bounded vocabulary rather than every valid value in the wider topic.
meaning = storedTable[exactSupportedToken] Field order, units and branch conditions follow the implementation explanation above.
| Exact supported token | Stored meaning |
|---|---|
| multiply | separable darkening |
| screen | separable lightening |
| overlay | separable contrast |
| difference | separable comparison |
| hue | nonseparable hue |
| saturation | nonseparable saturation |
| color | nonseparable color |
| luminosity | nonseparable luminosity |
| normal | normal source-over compositing |
| Output field | Meaning | Value type |
|---|---|---|
| meaning | Stored explanation for the exact supported token. | string |

}Limitations and assumptions
A family label does not calculate pixels or perform alpha compositing. Apply the exact scope and assumptions described above.
All listed fields require explicit values. Unexpected fields, incorrect types, nonfinite numbers and sparse arrays fail validation. Domain-specific bounds, alignments and supported tokens are stated above; extremely large inputs or outputs can also be rejected. These errors differ from successful results such as false, no matches or unknown evidence.
