Permanent Pink FL
PR187
Alternate Names
Carl’s Crimson
Naphthol Red HF4B
Pigment Description
This is the famed Carl's Crimson. A LF rating of II. This is a fun red that makes some interesting tints and blends. However the ASTM II rating is not as high as we'd like to see, so we would not wholesale recommend it based on moderate lightfastness.
