Excerpt from the text: "The following characteristic of warm tints is of especial note: With increasing light, the luminosity of the warmer tints grows more rapid than that of the colder tones. In the brightest and strongest sunlight, all tints assume a whitish appearance, without losing their character of warmth or cold. By decreasing light, the warm tints lose their luminosity more rapidly than the cold tones; by continued decreasing of the light, the luminosity of bright red will at a certain stage equal that of a cold violet, and from this down will appear darker than the latter." An exceptionally scarce paint trade piece.
