Titanium dioxide and zinc white are the most common pigments used to create opaque white hues in acrylics. These pigments are mixed with an acrylic polymer emulsion binder, which gives the paint its characteristic quick-drying properties and allows for easy cleanup with water. Different manufacturers offer variations, resulting in a range of whites with subtle differences in opacity, undertone, and texture. For instance, titanium white typically offers greater opacity, while zinc white can be more transparent and is often preferred for mixing and glazing.
A pure, bright white serves as a crucial foundation in painting. It provides the brightest value in the palette, allowing artists to create highlights, mix tints of other colors, and adjust tonal values within a composition. Historically, lead white was widely used but due to its toxicity, it has been largely replaced by safer titanium and zinc-based alternatives. The development of non-toxic, vibrant whites has broadened artistic possibilities, offering a safe and versatile tool for achieving luminosity and depth in acrylic paintings.
