Underpainting

Underpainting is an initial layer of paint applied to a canvas or surface, serving as a foundation for a more detailed artwork. Artists often use a single tone or monochromatic palette to sketch out the composition, values, and shapes. This underlying layer guides the subsequent layers of color and detail, helping to establish depth, contrast, and composition early in the process. Think of it as a preliminary blueprint for a painting that ensures the final work has coherence and structure. Underpainting is a common technique in oil and acrylic painting, enriching the final piece with depth and vibrancy.
