Hi Pamela,

About Bellini Lead Yellow.
Sennelier may have a lead or lead-tin yellow.
The color itself is very opaque and pale. I'm glad I still have a tube of Bellini's left. Cad Lemon yellow and white will come close. Grumbacher Cadmium Barium Yellow Pale and white will come closer.

Go here and scroll down to the Interactive Real Color Wheel Matching Tube Pigment Colors in RGB and YMC.

You can click the radio buttons and see the differences of the colors.
Belleni is out of business, Permenant Pigments is Liquitex and that line may be gone also. Bocour is gone, all the good ones are gone.

Carbozle Dioxazine Purple or Grumbacher Thalo Purple all are the same pigment. PV15 is the Pigment Color Index Number, that is how you should really search and buy colors, brand names really don't mean much.

Yes it is listed as Mussini Opaque Green Light.

Some W/N colors are too far off, Their cyan is a red side if I remember right. Grumbacher has a great cyan, Thalo blue.

This is another good pigment page, it has the Pigment Index numbers.

New Question?  Is Liquitex still making oils?  I did a search and didn't find them...if not, what brand should I substitute for the Diox. Purple on the palette list?
Thanks, Pamela
