How to Activate Metallic Watercolors: Step-by-Step Guide

How much water, how long to wait, and how to get full opacity and intense sparkle in a single brushstroke.

Activating metallic watercolors correctly makes all the difference. Pigments vary, so colors behave differently, and you need to get a feel for the right consistency. The four steps below work for our entire range.

Why activation matters

If you brush over a dry pan right away, you pick up only a fraction of the pigment. The result looks watery and thin and barely sparkles. Taking a few minutes to activate the paint gives you full opacity and sparkle.

Step 1: Add 1 to 2 drops of water

Place one to two drops of water directly on the surface of the paint. The amount matters. With too much water the pigment density drops and the color turns translucent. With too little, the brush can't pick up enough paint. One to two drops are right for one pan.

Step 2: Wait 3 to 5 minutes

Let the water sit for three to five minutes so it can absorb enough pigment. This is the step most people skip. They start painting right away and wonder why the color is watery and does not cover.

Step 3: Mix to a creamy consistency

Mix water and paint with your brush until the paint is smooth and creamy, and pick up plenty of pigment as you go. If the brush feels dry or the paint looks streaky, add another small drop of water and keep mixing.

Step 4: Paint

Apply the paint to your watercolor paper. A single stroke should be fully opaque and sparkle intensely under direct light, on white and on black paper.

Adjusting pigment density

Once your colors are activated, you can control the density with water. Use them fully opaque, semi-opaque, or as a light glitter over areas you have painted with regular watercolors first. I always recommend activating fully first and diluting from there.

The other half: light

Activation decides how much pigment reaches the paper. Light decides how it looks. Even a perfectly activated metallic or holo color looks flat and gray without a direct light source. The sparkle, and with our holo colors the rainbow effect, appears only when light hits the pigment directly. Look at your painting under a lamp or in sunlight, and photograph it there too.

Common mistakes

• Starting right away: the paint stays watery. Wait the full 3 to 5 minutes.
• Too much water: the color turns translucent. Start with one drop and add more only if needed.
• Judging the color in diffuse light: metallic colors need direct light to sparkle.
