Comparing colors in oils and acrylics

[Vianna Szabo]

Thank you Pam,
That is important information to know. I usually make value and color shift decisions on the palette and will have to adjust for that. How much does the value change and does the amount of medium affect them as well?

I worked for another artist in his studio using acrylics, His philosophy was that any mistakes could be covered by another layer of paint but I found it got muddy if you were not sensitve to the preceding layer.
