What technique can help blend the edges of different paint colors?

Feathering is a technique that involves gradually blending the edges of different paint colors to create a smooth transition between them. This method is often used in painting to soften the distinct lines that can occur when two paint colors meet. By applying paint with a brush in a light, sweeping motion at the edges, the colors can be blended effectively, helping to eliminate any harsh divisions.

Feathering is particularly useful in creating gradients or in decorative painting where a more cohesive look is desired. It can also be beneficial in touch-ups where a seamless appearance is important. The subtlety of this technique allows for enhanced visual appeal and professionalism in the finished work.

Other techniques, while valuable in their own right, serve different purposes. Layering involves applying multiple coats or colors in succession, which can create depth but does not specifically focus on blending edges. Sponging adds texture and can introduce color variation but does not effectively achieve a smooth transition. Dry brushing emphasizes texture by using a dry brush to lightly apply paint, resulting in a more weathered look, which is not aimed at blending. Thus, feathering is the technique specifically designed for the gradual blending of paint colors.
