What is the technique of painting called in which glue mixed opaque colour is used ?

Question

Accepted Answer

The technique of painting in which glue mixed with opaque color is used is known as "Gouache." Here is a detailed explanation supporting why Option 2 is the correct answer:

1. **Explanation for Option 2 (Gouache):**
   - Gouache is a painting technique that involves using opaque pigments mixed with a binding agent, typically gum arabic, and sometimes glue. This mixture allows the paint to be more opaque than watercolor, providing a solid, matte finish. The addition of glue or other binding agents helps the paint adhere better to the surface and enhances its opacity. Gouache is favored for its vibrant colors and ability to cover previous layers, making it a popular choice for illustrations, posters, and design work.

2. **Explanation for why other options are incorrect:**

- **Option 1 (Wash):**
     - A wash is a technique used in watercolor painting where a thin, transparent layer of color is applied. It involves diluting the paint with water to create a light, translucent effect. Unlike gouache, a wash does not use opaque colors or glue, and its purpose is to create a soft, blended appearance rather than a solid, opaque one.

- **Option 3 (Collage):**
     - Collage is an art technique that involves assembling various materials such as paper, fabric, or other objects onto a surface to create a new composition. It is not a painting technique and does not involve the use of glue mixed with opaque colors. Instead, glue is used to adhere different materials together.

- **Option 4 (None of these):**
     - This option is incorrect because the technique described in the question is specifically known as gouache, as explained above. Therefore, "None of these" does not apply since Option 2 correctly identifies the technique.

In conclusion, the correct answer is Option 2, Gouache, because it accurately describes the painting technique involving glue mixed with opaque color. The other options do not fit the description provided in the question.
