Ultramarine Violet
4 of 436RCW#18, Transparent, PV:15
Ultramarine Violet is opposite Yellow-Green
CYYY, Old Holland Yellow-Green Organic Opaque
If the yellow-green were transparent the two would mix dark-neutral,
if we had the color but we haven't gotten it yet in oil, 2009.
I don't load this color, it's too weak.
