My gamblins ivory black oozes oil so bad that its funny. Meanwhile, WN lamp black and also ivory black behaves nicely, no oozing. I've had a WN tube oozing also, but that comes and goes depending on where on the tube i am pulling from, its hansa yellow light. But saying all that, personal thing, if is just a little bit of oil separation on dark colors, its tootally fine for me. I would have a problem it my main dense colors were oozing, mainly titanium white or yellow ocher.... those I need to be dense and opaque and rich texture.... the dark colors i prefer to be less textured anyway, so I do find the little bit of oil separation useful in some cases for the darker colors. I was impressed the most with the phtalo turquoise from gamblin, very useful color to be a second blue with the Ultramarine. The green and the regular phtalo blue are nice too, but for me, the green is too much far from any earthly found colors, and the phthalo blue is just closer to UB in hue, so the phthalo turquoise being farther apart would be my choice. Sorry for any grammar, from brazil here!
