With just a few drops of water, you can make bold, saturated marks on wet or dry paper. To make typical, translucent watercolor washes, you'll need to add more water than you might expect. Most Tonic colors start out semi-opaque because of their high pigment load, but they open up with water, becoming light and subtle as they're diluted.
At any concentration, Tonic is free-flowing. It's easy to load onto a wet brush, easy to lift from its pan or from paper, and easy to move the brush across watercolor paper. Some brands of watercolor are too sticky or slow-moving to allow painting on dry paper, but with Tonic, you don't need to pre-wet the page for most techniques.
