Question

What is the difference between Tempara & Guachi, what do you
mean by the clearity of water colour. What do you mean by opeque
of the painting?​

Answer 1

Upon first inspection, watercolor and gouache (pronounced “gwash”) may appear to be nearly identical mediums. However, when given more attention, one can see that both paints have individual characteristics that make them easy to distinguish. A primary difference between the two paints is that gouache is more opaque than watercolor. When a layer of watercolor is applied, the white paper and any preliminary drawings underneath will show through, whereas when a layer of gouache is applied, the paper will not show through nearly as much. Due to the transparency of watercolor, the light is able to travel through the pigment and reflect off of the white paper, giving it a luminous quality that differs from gouache’s matte finish.

Despite these differing properties, watercolor and gouache are nearly identical in makeup. Both paints consist of pigment and water soluble binder, which allows the paint to be altered even after it dries with the addition of water. The opacity of gouache comes from the white pigment or chalk that is added along with the colored pigment and binder in order to make it less transparent.

Answer 2

Answer:

Tempera paint is a water soluble opaque paint. Tempera is pigment (powdered color) mixed with glue, egg (traditional) or milk. It is most often used for children's art because of its economy, easy soap and water clean up and low toxicity.

Gouache is water soluble opaque paint. It is made fron pigment combined with gum arabic. Usually purchased in tube form it can be thinned with water.

It is most often used by illustrators and fine artist studies. It can be expensive. Used for accurate, quick drying opaque color that will clean up with soap and water.

Watercolor is a transparent water soluble paint. Like gouache, it consists of pigment and gum arabic. Sold as hard cakes or in tubes, it can be thinned with water. Watercolor is transparent and creates brilliant color.
