What are the characteristics of oil paints?
Oil paints are basically pigments that are suspended in linseed oil. In most cases oil paints come in basic colors, and it is upon the artist to mix the colors to get the right shade of color. That is why when you are starting out on oil painting, it is advisable to stock up a tube of black and white paint in bigger quantities as compared to the other colors.
You will also find that till you get the hang of mixing two or more paint colors to get the exact shade you want, you will be spending more on paints and more time on doing this. You will realize that getting the shades that you want on your paintings may actually be more difficult than you thought in the first place.
In some cases, you will find that you have a large area to paint using the same mix of colors but it is not such a good idea to mix a huge batch at once as this may cause the paint to dry and go waste. You can only do this if you are planning on painting that whole part of the painting at once. However, you can make note of the actual proportions that you used the first time so that you get it right the next time you want to mix it.
With practice you will get the hang of this and since oil paints of good quality tend to be a bit expensive, it is a good idea to buy cheaper ones when you are just getting started. Once you are completely well versed at this, you can go out and splurge on some expensive paints. You will find that good quality of oil paints that you use will only enhance the quality and look of the end product.
