Thankfully this color is still available. It was temporarily discontinued due to pigment availability issues in 2020. A new supply was found, and this color was reinstated in 2021. When it looked like the pigment would not be available, Golden recommended the following: “Also, “it is possible to create mixtures in the same general color space. QoR Pyrrole Red Light (PR 255), and Quinacridone Red Light (PR 207) are good starting points. Either of these will need to be modified with a touch of orange. We tested both Cadmium Orange (PO 20) and Transparent Pyrrole Orange (PO 71). Of the two oranges, we prefer Transparent Pyrrole Orange due to its transparency and the mixes it makes. Quinacridone Red Light creates mixes a bit too bright, and Pyrrole Red Light creates mixes that are not quite bright enough. Combining these two reds and adding orange creates a color closer to the target.

We recommend approximately equal amounts of Quinacridone Red Light and Pyrrole Red Light mixed together with a tiny bit of Transparent Pyrrole Orange to approximate the glowing color of QoR Permanent Scarlet.“ -Golden
