What is a key characteristic of the glazing technique?

A key characteristic of the glazing technique is its ability to produce brilliant and deep color application. This technique involves applying multiple thin layers of transparent paint over a dried layer, which allows the underlying colors and textures to shine through. The transparency of the glaze results in a vibrant depth that enhances the overall richness of the colors, creating a luminous effect that is highly prized in painting.

While adding thick layers of paint may lead to a different textural effect, it does not align with the glazing method, which relies on thin, translucent applications. Working primarily with a single color does not capture the essence of glazing either, as this technique typically involves multiple colors layered to generate complex optical effects. Creating a rough texture on canvas is also not characteristic of glazing; instead, this technique often seeks to achieve a smoother, more luminous surface through careful layering. Thus, the correct option emphasizes the unique quality of color richness that glazing brings to a painting.
