Description
Accept L*, a* or b* coordinate.
Food-process terms can describe heat, flow, texture, color or gas behavior under a chosen model. A local factor or physical ratio is different from validating the full process, product quality or microbiological safety.
Accept L*, a* or b* coordinate.
When to use this tool
Use Food Color Lab One Coordinate Gap when you need one explicit food-process or physical-model term.
How to use the tool and how it works
- Enter measured, reference, coordinate. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read signedGap, absoluteGap, coordinate. Use the output convention below.
Accept L*, a* or b* coordinate. Return measured-reference, its magnitude and the coordinate label.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| measured | Measured | Required. Finite number. |
| reference | Caller-supplied comparator on the same measurement or valuation basis. | Required. Finite number. |
| coordinate | One literal CIELAB coordinate, L*, a* or b*; no complete ΔE is calculated. | Required. Text; one of "L*", "a*", "b*"; maximum UTF-16 length 8192. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| signedGap | Signed Gap | Required. Finite number. |
| absoluteGap | Absolute Gap | Required. Finite number. |
| coordinate | One literal CIELAB coordinate, L*, a* or b*; no complete ΔE is calculated. | Required. Text; maximum UTF-16 length 8192. |

}Limitations and assumptions
- This is one supplied CIELAB coordinate gap, not a complete ΔE color difference, calibrated color measurement or sensory acceptability verdict.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use the complete validated process and measurement method for practical decisions. Review calibration, composition, uncertainty and omitted mechanisms before interpreting a local estimate.

Subtract baselineForce times distance from measuredArea, then subtract referenceArea for the gap.
