Beginner’s (and others) guide to choosing colors
Having the right colors is crucial to be able to mix with them. Most watercolor sets have a decent range of colors, but they often lack some important color, and it also often includes several unnecessary ones.
I will present the 11 colors that I expect all my students to have and which are a good starting point for all types of color mixes. Note that this is not a “personal” palette, it is a palette to mix with, all colors are selected according to their hue and mixing properties.
We start with the three primary colors, these are a must have. They are important because you can mix them to any other color. It is also very important to choose the right one here, for example it does not work with any blue, it should be the blue color that is closest to the primary blue and has a pure hue.
Must be a lemon yellow color, a cold yellow color. I think the best is PY175 (benzimidazolone) which has different names from different manufacturers, (See the list at the end of the article.)
There is only one: Quinacridone Rose, the index name is PV19 (RS) manufacturers often call it Quinacridone Rose or Premanent rose.
The same as for red color also applies to blue, there are no alternatives to Phthalo blue red shade. It is the perfect primary blue color, no other is as good primary blue.
Thus, the three primary colors are completed, now: some other colors.
Phthalo Green Yellow Shade is the perfect complementary color to the primary red Quinacridone Rose, therefore you should have it, it is very good to have a complementary color to red and Phthalo Green (YS) is perfect. If you, like most people, have a Phthalo green blue shade, it will do, mixtures with the red will be a little violet, so it is better with the yellow shade, but blue shade will do, when the pan or tube is empty you buy yellow shade.
Warm yellow and warm red
Since the eye is sensitive in the yellow-red register, it can be good to also have a warm yellow and red at your disposal. Namely, it is difficult to make nice color mixtures in this area with only a cold yellow and a cold red. Any warm yellow and red will do, my favorites are Nickel Azo Yellow (PY150) from Daniel Smith and Transparent Pyrrol Orange also from Daniel Smith.
More blue colors
Just because blue is so important to me, I want to include some blue options. Phthalo blue is perfect as a primary color, but it is at the same time dull and flat. French ultramarine is a much nicer watercolor. It is too red to be a primary color, but it expands the palette with several new mixing options, so it is important. I think you should also have cobalt blue, a slightly milky light color with great potential for interesting mixtures.
There are lots of good brown colors but only two that one must have: burnt sienna and raw sienna, They are light brown colors, it is good because it is easy to make a light color dark, but the reverse is impossible. So if you are only going to have two browns, it should be these. In watercolor sets, the yellow-brown color is usually ocher, not sienna. If you have such a box, you should of course use the opaque yellow ocher until it runs out but then buy a transparent raw sienna.
Black color is important, without it, it is not possible to lower the value of other colors without changing their hue. The black should be neutral, Only two colors are common and work as black in the watercolor box: Ivory black and lamp black. Ivory black is transparent and easy to mix with other colors, while lamp black is more opaque and not as good, so the choice is simple, it will be ivory black.
If you understand the color wheel and own these 11 colors, you have the opportunity to mix all the colors you need. As I mentioned earlier, this is not a “personal” palette, you will probably grow out of it over time, but it is a good basis for color mixes, it is very versatile .
