How to properly use watercolor Dot Cards
Dot Cards are not just color samples. They are real watercolor paint, dried onto paper, and they function like a compact testing laboratory. Everything you see there—intensity, transparency, granulation, behavior in water—is exactly what you will get from the tube.
Using them correctly starts simply. Lightly wet your brush, gently touch the dot, and let the color activate on its own. Do not rub or press. The paint needs a little time to “wake up,” just as it does on a palette.
Instead of limiting yourself to simple swatches, try different applications: a diluted wash, a more concentrated stroke, wet-on-dry and wet-on-wet. That is where you will see how the pigment moves, whether it granulates, how much it stains the paper, and how it behaves in layers.
Dot Cards are also ideal for mixing. You can test combinations, understand whether two colors harmonize or turn muddy, and explore warm and cool relationships without commitment. Even better, use them for small sketches—a leaf, a cloud, a shadow. At such a small scale, you immediately understand whether a color truly suits you.
The main reason Dot Cards are so useful is that they help you choose consciously. You are not relying on photos or names. You see how the color works on your own paper, with your own brush, and in your own way.
Keep them as a reference archive. Note impressions, mixes, techniques. Over time, you will build a personal color journal that is more valuable than any ready-made chart.
Dot Cards are not demos. They are education in miniature. And when used correctly, they change the way you choose and think about color.
