Could you please let me know the pigment number of this colour - Rose Madder? I have a colour from Art Spectrum called Permanent Rose PY19 and was wondering how this Rose Madder differs from it. Tx
The pigment composition of this colour is PR177/PR48:2.
Also, I am unsure whether you mistyped or misread your label but the pigment in Art Spectrum Permanent Rose is PV19, I only mention this to aid your search further.
All the best,
