To paint on paper with thin transparent layer of water colour is known as :

Question

Accepted Answer

To paint on paper with a thin transparent layer of watercolor is known as "wash painting." Let's explore why Option 4 is the correct answer and why the other options are incorrect:

1. **Explanation for Option 4 (Wash painting):**
   - Wash painting involves applying a thin, transparent layer of watercolor to a surface, typically paper. This technique allows the underlying surface or previous layers of paint to show through, creating a luminous effect. The transparency is achieved by diluting the paint with water, which is a hallmark of watercolor techniques. Wash painting is often used to create soft backgrounds, subtle gradients, and atmospheric effects in artworks.

2. **Why Option 1 (Tempera painting) is incorrect:**
   - Tempera painting is a technique that uses pigments mixed with a water-soluble binder medium such as egg yolk. It is known for its fast-drying properties and is typically applied in opaque layers rather than thin, transparent washes. Tempera is more commonly used on rigid surfaces like wood panels rather than paper.

3. **Why Option 2 (Pure colour painting) is incorrect:**
   - Pure color painting is not a specific term associated with watercolor techniques. It generally refers to the use of unmixed, vibrant colors in painting. This term does not specifically describe the method of applying thin, transparent layers of paint, which is characteristic of wash painting.

4. **Why Option 3 (Poster painting) is incorrect:**
   - Poster painting typically involves the use of opaque paints, such as gouache or poster colors, which are designed to provide solid coverage and vibrant colors. These paints are not transparent and are used to create bold, eye-catching designs. This is contrary to the transparent nature of wash painting with watercolors.

In conclusion, wash painting is the correct term for the technique of applying thin, transparent layers of watercolor on paper, making Option 4 the accurate choice.
