Re: Need Help / inks
when you want to try marbling with oil based paints, just do it. What works for others doesn't necessarily work for you anyway (and vice versa), everyone needs to make their own experience. There are so many parameters to marbling, paints are only one of them and the manufacturer of paints just another. There is no universal-one-fits-for-all paint.
That oil based paints are usually brighter does not depend on a certain brand.
