Art can be such a therapeutic and useful outlet for many individuals. It allows your to express your personality and style through whatever artistic channel you find, including that of drawing and painting with oil paints. The use of said oil paints can enable the artist to use several different pigments and oils, for that matter, to portray exactly what they want through their art.
The art of painting with oil paints can be a tricky one to adapt to and acquire, as the oil paint and pigments can age and react differently depending on what is used and other materials. In all honesty, the artist can truly make whatever colors they would like to use, depending on which pigments they mix with certain oils (like walnut oil and safflower oil to name a few), and how much is mixed together. Painting with oil paints can also take a while to dry, usually about 1 to 3 weeks, depending on how much is used and to what extent.
Painting with oil paints can make a beautiful piece of artwork. In fact, many famous painting that we have seen throughout history were made with the same techniques (i.e. The Mona Lisa). As said before, the techniques to use for oil paints can be tricky to get used to, but can result in a most beautiful piece of art in the end.
