Using Black and White a Cautionary Tale

   How to Use Black and White in Oil Painting

    One thing that happens with mixing paint is people reach for white or black too quickly when they are mixing colors. The biggest thing to remember is white or black will desaturate your color mixtures very quickly. When mixing your colors mix your hue first remember the colors your mix together will affect the value and chroma of the final color mixture. Get as close to the color you need before you add white. Also remember when you add white the color will get lighter but will also get cooler oranges, yellows and reds will shift more than other colors. So if I am adding white to an orange mixture the mixture will get cooler. After adding white I will have to add a warm yellow to shift the mixture warmer. It’s intuitive like with cooking you make the soup and then taste it sometimes it needs a little more salt, pepper or whatever. It’s the same thing with mixing color. Just remember to add white at the end of your mixture. To avoid times when you might add white to early in a mixture. If I am creating a very light blue green for instance and using a dark blue such as thalo or ultramarine. These colors are so dark in value it is hard to see what the color is doing when it is so dark. I could lighten the mixture with lemon yellow but that will also shift the mixture more yellow. I might add a little white to make the blue higher in value just so I can see the hue a little clearer and control my mixture much better.
The paint color Black has gotten a bad rap over the years. There are two camps those that swear that black should never find its way onto your palette and others that say good paintings can’t be done without it. I say good paintings can be done with or without black. I do enjoy having black on my palette. You can certainly paint without black and many great artists don’t use black. However there are just as many great colorists and impressionists who used black including Degas, Manet, Zorn and others. The best thing to remember is add black to a color mixture containing one or two other colors. Avoid having white in the mixture since that will lower the chroma or intensity of the mixture considerably. Use black with a transparent color like alizarin crimson or ultramarine blue and others this will give the black more translucency and add some depth to the black. Also remember in your mixtures that black is nothing more than a very dark low intensity blue. So remember black is a blue use it that way in your mixtures.
By understanding how to use white and black and how they affect your color mixtures you can use them effectively to lower and lighten the value of your colors while controlling their intensity. This will give your paintings more depth.
