Analyze the question stem

The question asks: "For which type of paint is the following true: They can be painted wet-on-wet, with a new color painted into a color that is not yet dry?"

Evaluate the options

• Gouache: A water-based matte paint. While it can be worked wet-on-wet, it dries very quickly, making extensive wet-on-wet blending difficult compared to slow-drying media.
• Encaustic: Uses heated beeswax as a binder. It cools and solidifies almost instantly, so it does not support wet-on-wet blending in a liquid state for long.
• Tempera: Typically egg tempera, which dries extremely fast via evaporation and is applied in thin, hatched strokes rather than wet-on-wet blends.
• Oil: A slow-drying medium using drying oils (like linseed oil) as a binder. This slow drying time is uniquely suited for the "wet-on-wet" (alla prima) technique, where wet paint is applied directly into or over another layer of wet paint, allowing seamless blending on the canvas.
• Acrylic: Dries relatively quickly by water evaporation, limiting the window for wet-on-wet blending without retarders.

Determine the correct choice

Oil paint is the classic medium most famously defined by and associated with the wet-on-wet technique due to its exceptionally long drying time.

Answer:

• (A) gouache
• (B) encaustic
• (C) tempera
• (D) oil (Correct answer)
• (E) acrylic
