If you look closely, at oil paint colored paintings, and then at watercolor based paintings, you will find that oil paintings have a more distinct coloring than do watercolors. However, this is not a wrong thing because some paintings need a certain fluidity of movement that watercolors lend themselves easily than do oil paints or acrylic paints. There is certain ease of flow in the way watercolors are used to paint mind-blowing paintings.
When you look at some paintings that have the water element in them using watercolors, the effect seems to be even more pronounced than when the same painting is made using acrylics or oil paints. Another thing that you should remember that watercolors when used for paintings tend to lend themselves in an easier manner to dilution and mixing. It is also true that the process of creating mind-blowing watercolor paintings takes more time because the artist has to wait for one layer of paints to dry before applying another. This time can come in handy for the artist to contemplate the work he or she has done until now to make changes if required.
