Dataset: Invariant categorical color regions across illuminant change coincide with focal colors

<p>Experimental data for a paper titled &quot;Invariant categorical color regions across illuminant change coincide with focal colors&ldquo; published in Journal of Vision.</p> <p>This repository contains following data. Please refer to the article for details about the dataset.</p> <p>&nbsp;</p> <p><strong>1. IlluminantsANDReflectances.xlsx</strong></p> <p>This file stores spectral radiance for each illuminant and OSA coordinates (jgL) and reflectance values for 424 OSA color samples.</p> <p>&nbsp;</p> <p><strong>2. Exp1_1_RawData</strong></p> <p>Raw data for Experiment 1-1.</p> <p>This folder has xlsx files, and filename indicates the illuminant condiion.</p> <p>In each xlsx file, different sheets contain a different observer&rsquo;s data.</p> <p>The number (1-424) corresponds to the number of OSA sample (shown in IlluminantsANDReflectances.xlsx).</p> <p>&nbsp;</p> <p><strong>3. Exp1_2_RawData</strong></p> <p>Raw data for Experiment 1-2. The same format as Exp1_1_RawData.</p> <p>&nbsp;</p> <p><strong>4. Exp2_RawData.xlsx</strong></p> <p>Raw matching data for Experiment 2.</p> <p>The name of each sheet shows the observer &amp; illuminant condition.</p> <p>Each row shows Ljg coordinates of the OSA sample and associated matching result (in RGB and xyL).</p>
