You can use regular acrylics as well if you are painting with oil on top. Just dont paint with acrylic on top of oil. Oil should always be last.
Also check out golden acrylics homepage, they should have a site where they test lots of things, not just their own colors, and post the test results.
Their acrylics are really expensive, bit they have lots of pigment.
If you are thinking of doing oil grounds you may just create the color yourself. It's literally just pigment and oil. Makes it cheaper if you are in need of bigger amounts.
Some pigments should not enter your lungs at all, because they are super toxic. Look up proper safety measures.
