CI Name NR28

CI stands for "Color Index". It's a short code that easily identifies the pigment. Not all pigments have one.

  • N designates that this is a naturally occuring pigment, composed of plant, animal, or organic natural earths.
  • R is shorthand for Red.
  • 28 is the CI serial number.
Toxicity Low

The general rule of thumb to follow is to not inhale, ingest, feed to pets or babies, pour on the ground, or leave on skin.

All pigments should be assumed to be dangerous, and potentially lethal if mishandled. If the pigment has high or extreme toxicity, it might be better not to use it at all.

Lightfastness IV Poor (Fugitive)

Blue wool 2-3. The pigment begins to fade in 2 to 15 years, even with proper mounting and display. (Not suitable for artistic use.)
