Choosing the right kind of paint is like falling in love… you just know it when it happens, and it feels as if no other paint would do. The reasons are a combination of personality, skills, confidence and knowledge of the medium itself.
Oils
Oil-based paint is typically slow-drying, consisting of particle pigments suspended in linseed oil. Brightness and glossiness is enhanced by adding turpentine, white spirit, varnish or other alcohol-based thinners.
what makes oils desirable is the durability of the paint and its versatility, as it can be used on canvas as well as other interior and exterior surfaces such as wood and metal. ![]()
When it comes to canvas applications, the amount of paint and the patience to apply it with the right timing and strokes, often bears splendid results and the prospect of enjoying the resulting artwork for a very long time.
One of the concerns when using oils extensively is the occasional presence of potentially toxic pigments, among which lead is the one typically at the center of attention. Modern pigments however have evolved to a point where health risks are significantly reduced, through the use of less toxic zinc or titanium-based pigments.
Watercolors
The desirable feature of watercolors is in the transparency. All watercolors, except for Guache, are transparent on some level, and are made of four main components:
The Pigment is a natural, synthetic, mineral or organic powder suspended in the Binder, a suspension liquid made of Arabic gum. Additives like glycerin, ox gall or honey are used as preservatives and to alter the transparency, viscosity and other properties of the paint. The Solvent is used to dilute the paint and it evaporates as the paint dries.
Enthusiasts of water-based paint are known to appreciate the paint best when it is not diluted with extra solvents, as watercolors are made to be used in their full range of paint consistency, and use dilution only when necessary.![]()
One of the concerns from painters attempting to use watercolors for the first time, is typically how fast the paint dries. The time allowed to mix colors directly on canvas is considerably less than what oils allow, which is why many develop quickly a habit of pre-mixing a certain palette range in paint wells. This may be considered a disadvantage by some, and yet, also a way to develop and broad knowledge of color mixing.
One common misconception around watercolors is that oils are believed to be significantly more resistant to light exposure. This is actually very inaccurate, as modern watercolors, Guache and acrylics have evolved to a point that many water-based paints produce artwork able to withstand light exposure and retain its original properties, even better than oils, especially when coupled with archival paper.
Considerations:
Art is expression, it’s a feeling, and there is no rule set in stone that should stir a painter from using one medium versus another. When considerable knowledge is gained in understanding advantages and disadvantages in using oils as well watercolors, it all comes down to the artist’s personal choice. For some it’s a love/hate thing, others will not care, as long as the paint allows them to feel free to express their vision.
