PAINT AND PIGMENT REFERANCE TABLE KEY:

Opacity:  1 = Opaque,   2 = Semi-Opaque,   3 = Semi-Transparent,   4 = Transparent

Light Fastness Rating:   I = Excellent,   II = Good,   III = Poor,   IV = Fugitive/Very Poor

Oil Absorption: (ml/100mg)
When the specific numbers are unavailable:   H = High,   M = Medium,   L = Low

Toxicity:  A = Low hazard;   B = Possible Hazard;  C = Hazardous;   D = Extremely Toxic;

(hue) = Refers to a hue color not designated on the label, when the word Hue is not in parenthesis is part of the pigment name as per ASTM guidelines.

? = a question mark next to a name, note, or data code indicates that it may or may not be correct information due to conflicting information, questionable reference, possible typo or other discrepancies in the manufacturer or other reference documentation. Further study is needed to clarify.

†Possible effects of long term light exposure are given when known, this may allow an artist to anticipate color changes and possibly use them as an advantage. These effects are all relative to the pigments inherent light fastness and may take decades or even centuries in normal conditions to be visible.
Fades = Becomes more Transparent; Lightens = Loses chroma but maintains relative transparency or opaque character; Whitens = Becomes lighter and more opaque; Darkens = Becomes darker but retains hue; Dulls = Loses chroma towards nuetral; Blackens = Turns very dark or black losing chroma; Hue shift = Changes hue towards a different color
