<p>An image of the yellows card used for testing is shown in A with the CAMP<sub>4</sub> (Classification Accuracy for Multiple Phones, 4 phones) shown in B. Results are presented for mappings developed using the Classic card and training yellows card (with images of the cards in the legend) as a function of the average minimum xy separation for different point subsets of the test yellows card with no ambient light. Note the increase in classification accuracy for small xy separations when the yellows card approach was used, crucial when trying to discriminate between very similar colors.</p>
