Color Spotlight: Transparent Pyrrol Orange (PO71)
PO71 oranges are highly transparent and very vibrant oranges! The Daniel Smith version pictured here is more reddish than some of the others. That said, it should be noted that I bought the DS TPO in 2022, so it’s one of the newer iterations. I am told that the older version was even more red and a bit more muted and earthy.
