Perylene Red
Synthetic Iron Oxide Red
This color may be a bit of a surprise as it is a deep crimson red. Like the similarly-named Capucine Yellow Deep, this color is a blend of a crimson (PR149) and a red earth (PR101). The PR149 component seems to be a pigment that comes in two kinds: light and deep. Winsor and Newton sells both PR149 varieties (for context) called Winsor Red and Winsor Red Deep. This Blockx color is going to be different from those as it is a special blend with PR101.
A general note on binding oils: some of the paints in Blockx’s range are bound in linseed oil and some are bound in poppyseed oil. An artist should educate themselves on the benefits and drawbacks of both oils. In general, linseed oil tends to form strong paint films, and poppyseed oil is not known for this. Linseed oil tends to yellow, and one of the main draws to poppyseed oil is that it resists yellowing to an amazing degree. However in some cases there are reports of problems with drying that are associated with poppyseed oil. Please research both oils so that you know what is right for your art practice. Blockx’s range is a gorgeously chromatic and unique addition to the world of oil paints, and we especially love their non-yellowing formulations in blues and purples.
