The problem with calling watercolor “unpredictable”

Watercolor is often described as unpredictable, and it is usually said with a certain tone. Half admiration, half warning. As if the medium itself cannot quite be trusted. As if it occasionally decides to do something on its own, outside of reason or skill.

The longer I work with watercolor, the less that word makes sense.

What is commonly called unpredictable is more accurately described as sensitive. Watercolor responds to conditions that are present whether or not we consciously register them. Moisture in the air. The absorbency of the paper on that particular day. How recently the paint was activated. How much water the brush carries without us noticing. How steady or tense the hand happens to be.

None of these variables are dramatic. But watercolor does not filter them out.

In many other media, small variations disappear into the process. Oil paint absorbs hesitation. Acrylic covers its tracks. Watercolor records what happens. It does not smooth things over. It leaves a trace.

Calling watercolor unpredictable creates a kind of distance. It suggests that the medium is acting independently, separate from the person working with it. But most of what ends up on the paper is a response to everything that was present in that moment. Including things that were not consciously chosen or controlled.

This is why watercolor can feel exposing. It shows timing. It shows restraint or lack of it. It shows when attention drifted, even briefly. It reflects conditions rather than intentions.

Once this is understood, frustration often softens. Not because the paint suddenly behaves more consistently, but because the expectation of repetition dissolves. The goal shifts. Instead of trying to recreate what happened last time, attention moves toward what is happening now.

Watercolor is not unpredictable. It is responsive. And that difference matters.
