The new color test.
The New Color Test allows estimation of the neutral zone (separation phase) and the characteristic color confusions (classification phase) using Munsell colors. The width of the neutral zone is estimated by the ranges of hues confused with grey. The severity of chromatic discrimination loss for a given axis is estimated by the range of chromas confused with grey.
