Which pigment type is characterized by being less prone to bleed but having lower hiding power?

The choice of organic pigments is accurate due to their unique characteristics. Organic pigments are typically composed of carbon-based compounds, which contribute to a range of vibrant colors and a lower tendency to bleed compared to other types. This reduced bleeding is essential in applications where color fastness and clarity are crucial.

However, organic pigments often exhibit lower hiding power, meaning they may require multiple coats to fully conceal the underlying surface or to achieve the desired color intensity. This is a critical consideration for contractors because it can affect the coverage, cost, and overall application process in a painting project.

In contrast, inorganic pigments are known for their excellent durability and opacity, often providing better hiding power but may have higher chances of bleeding depending on their formulation. Extender pigments, while useful in increasing volume or modifying properties without significantly adding to color, do not significantly contribute to color vibrancy or hiding capability. Barrier pigments are utilized for their protective qualities, particularly against environmental factors, but do not fit the description of being less prone to bleed with lower hiding power.

Thus, organic pigments are best recognized for their vibrant colors and management of bleed at the expense of hiding power, making the selection of this option valid.
