Using tubes of watercolor paint can be a bit different than using pans or cakes of watercolor. Here's a basic guide on how to use tubes of watercolor paint:
Materials Needed: You'll need your tubes of watercolor paint, watercolor paper (preferably 140lb or heavier to prevent warping), a palette for mixing colors, a container for water, and brushes. Watercolor brushes come in various shapes and sizes, but a good starting point would be a medium-sized round brush and a larger flat brush.
Setting Up Your Workspace: Arrange your materials in a way that's comfortable for you. You might want to have your water, palette, and paints on one side, and your paper on the other. Make sure you have plenty of clean water available for rinsing your brushes.
Squeeze Out Your Paints: If you haven't set up your palette already, visit this post to see how. Otherwise, you can squeeze a small amount of each color onto your palette or mixing surface. You don't need much - a little goes a long way with watercolors. Arrange them in the order they appear on the color chart that comes with the set, or in a way that makes sense to you. Wipe and close the tubes tightly after use to prevent the paint from drying out.
Mixing Colors: To mix colors, take a clean, wet brush and pick up some paint from one of your squeezed-out blobs. Transfer this to a clean spot on your palette and rinse your brush. Then pick up some paint from a different color and mix it with the first color. You can create a wide range of colors by mixing.
Applying Paint: Wet your brush and pick up some paint. Apply it to the paper. The more water you use, the lighter the color will be. For a darker, more saturated color, use less water. You can also create gradients by applying a lot of water and paint at one end of your paper, and gradually adding less as you move down.
Layering Colors: Watercolor is great for layering. To do this, apply a wash of color and let it dry completely. Then apply a second wash over the top. The colors will blend and create depth.
Cleaning Up: When you're done painting, make sure to clean your brushes thoroughly and let them dry horizontally on a towel. If you leave them in water, leave paint in them or let them dry vertically, it can damage the bristles.
Watercolor painting is all about practice and experimentation. Don't be afraid to try different techniques, mix colors, and make mistakes. That's all part of the learning process. Happy painting!
