The last color Camlin Ultramarine already contains Diox purple PV23 ant it is almost violet. So, you tried to mix PV23/PV37 using much of PV23. And Daniel Smith PV19 is not red, but reddish magenta color.
@@KaustavMukherjeeFineArt My first Quinacridone was PR122 magenta. I did PR122/Ultramarine PB29 mixing many times, mixed violet color is very clean and gorgeous!
These are romantic names given to a type of color by manufacturers. Most of the colors would contain a combo of the same pigments. E.g. madder Lake purple of Rembrandt is a mix of PR264 / PV19.
