The main difference between ®wOil and traditional oil color is ®wOil’s ability to thin and clean up with water in place of solvent that requires special care in handling and use. ®wOil can be thinned with water for painting, and all brushes and equipment can be cleaned with soap and water. The use of solvents is not necessary with ®wOil. Therefore, artists who are sensitive to solvents can enjoy using oil colors again without the use of solvents, allowing for a greener painting environment.
