Understanding the Cadmium Pigments
In the cadmium family of colors, there are usually 2 or 3 steps or levels.
In the yellow cadmium family this is usually Cadmium Yellow Light, Cadmium Yellow Medium and Cadmium Yellow Deep (or sometimes Dark).
And for the red cadmium family it is usually Cadmium Red Light, Cadmium Red Medium and Cadmium Red Deep (or sometimes Dark).
These names may vary by artist oil paint manufacturer, so be aware of this important point. You will want to get the right version of these important colors.
#1. Buy only Cadmium Yellow Light and Cadmium Red Light
Buying only these 2 colors will save you money with these very expensive pigments and and here's why:
You can easily go from cadmium yellow light to cadmium yellow medium or cadmium yellow deep (dark) just by adding a little red and maybe graying just a little.
Following the same idea, you can easily go from cadmium red light to cadmium red medium or cadmium red deep (dark) just by adding a little blue and maybe graying a little.
So it's easy to create the other 2 from the single light color. But you can't go back in the other direction.
In other words, you can't make Cadmium Yellow Light from Cadmium Yellow medium or Deep. And, of course, the same thing is true of Cadmium Red Medium or Deep.
Do you see?
So it really makes no sense to spend the extra money to have these colors in your palette. It's just another trick of the paint manufacturers to give you something else to spend your money on.
#2. Avoid Mixing White with the Cadmium Pigments
Basically, whenever you mix white with a color it will dilute it or make it weaker.
This is especially true of the cadmium pigments. The cadmium colors are not known for their tinting strength like other pigments. And so white really breaks down their essential color hue and color strength.
Cadmium pigments also become somewhat "chalky" when you mix them with white.
This is due mostly to the chemistry of the pigments and how they combine with other chemicals. Overall, it is not a happy mix.
Whenever possible, try using an analogous color to get a lighter value, such as for a highlight, or other lighter value.
So for example, when you need to go lighter for Cadmium Red, don't reach for white but try mixing Cadmium Yellow instead.
You will get a brighter and more vivid color rather than that chalky mix that is inevitable with mixing white.
Experiment to get the right results
You may have to experiment to get the right results with the suggestions above. But as an artist, you should be growing in your ability to mix colors and understand your color palette.
And after all, isn't experimenting with colors half the fun we have when we are painting.
