WLab robustness report

Will a match hold where the product is actually seen? Paste the spectral reflectance of a standard and its samples, choose the lights (and observers) that matter, and read how far each sample is from the standard under each one, as ΔEWLab. Everything runs in this page; nothing is sent anywhere.

1. Spectra

First column wavelength in nm, then one column per material; the first material is the standard. Comma, tab or semicolon separated, with or without a header row. Any range and interval from 380 to 780 nm; reflectance as 0–1 or in percent.

Show the reflectances

Paste or load spectra to see them here.

2. Lights and observers

The first condition is the reference (normally the viewing booth); the report also gives ΔE00 under it.

Add your own light (a measured spectrum)

Two columns: wavelength in nm and relative power, any scale. Any range and interval from 380 to 780 nm.
