Answer 2

Whether you’re painting with oils or watercolors, the paint itself starts with a dry pigment that is mixed with a binding liquid to hold the pigment together. Oil paint is created by mixing pigment with a type of oil, such as linseed or walnut oil; whereas watercolor paint uses gum arabic, a type of tree sap from the acacia tree, to bind the pigment.


Every Paint Has a Solution

Because oil does not dissolve in water, thinning or cleaning up oil paint involves the use of chemical solvents, such as turpentine. Painting with watercolor, on the other hand, uses water to control the opacity of the paint and depth of color. Watercolor paint is water-soluble, which offers a more natural and odor-free solution (a plus for children who are eager to paint).

It’s All About Technique

Oil is an opaque medium that can be applied thick or can be thinned out to produce a variety of depths (or even transparency). While a number of surfaces or materials can be used for oil paintings, canvas is the most common. The oil technique generally involves painting the darkest layer first, and then continuing the layers from lighter to lightest. The slow drying time of oil paint makes it a very forgiving medium—mistakes can easily be painted over or scraped off with a palette knife. Watercolor is a transparent medium that is often applied to paper, and is fast-drying. This painting technique is quite different from the oil method—painting watercolors involves starting from the lightest layers first and gradually getting darker. The effects of a watercolor brush stroke are immediate, as the paint bonds with the paper on contact. A great deal of patience and experimentation is needed for understanding the delicate interplay between water, paint, and paper and the best techniques for achieving the desired level of detail and depth of color. Chances are, you will go through many pages of watercolor paper as you discover the effects of blending colors, using different brushes and changing the amount of water. The great thing about painting is that you will find joy and beauty, even in your mistakes!
