Which paint medium allows layering and crisp lines?

• A. Watercolor
• B. Oil
• C. Acrylic
• D. Tempera

Answer: (B)

Oil paint stays workable for a long time, so you can blend and refine edges and build up multiple thin layers (glazes) to achieve depth while preserving crisp, controlled lines. The slow drying gives you time to sharpen edges and revisit details without lifting earlier work. By contrast, watercolor tends to bleed and soften edges, acrylic dries quickly (making precise lines harder without special techniques), and tempera dries almost instantly and doesn’t glaze well. So the combination of extended work time and easy edge control makes oil the best fit for layering and crisp lines.
