Pyrrole Orange PO73 pigment to handmade watercolor paint

This beautiful pigment I’m working with today is Pyrrole Orange PO73.

It’s a DPP pigment from @kremerpigmente , which stands for di-keto-pyrollo-pyrrol. Pyrrole comes from the Greek word pyrrhos, meaning fiery. 
It’s more opaque than other organic pigments but can still be used for beautiful washes in watercolor. Discovered in the 1980’s, the Pyrrole pigments are great and non toxic alternatives for the lead molybdate and cadmiums with in the red/orange pigment options. From the Kremer website: ‘’Because of growing concern about possible health hazards related to the use of cadmium pigments in the coatings industry, chemical companies have long sought after a possible organic substitute.’’
This PO73 is a great solution for those concerns. It’s the most chromatic pigment currently known. Chroma means how much color (or wavelengths) it reflects. It’s not an orange pigment with the highest value, or what we would consider as a ‘’brighter’’ orange. For me, I’d like Benzimidazolone PO62 for that. Which is more towards the yellow side of the spectrum, whereas PO73 is more of a scarlet-orange, leaning towards the red side of the spectrum. This is also visible in it’s spectral reflectance curve which I make in this video. 

Hue wise, is very close to PO43, Perinone Orange, which is just a little less chromatic and less lightfast. 

PO73 is a very staining color with a slight drying shift, meaning it loses saturation from wet to dry state in paper. 

As Bruce MacEvoy said on Handprint.com: “I have very high regard for this pigment; it is everything modern pigment chemistry should be. Provided you use the transparent single pigment brands, this makes a very versatile and reliable paint, worth trying for florals and other brilliant painting styles, and splendid as a warm, almost pinkish tint or blush color for caucasian flesh tones.”

I hope you liked this ''in your face'' orange process from dry pigment to handmade watercolor paint. I sure do!
