The difference between oil painting, watercolor and Gouache
oil paint
Oil painting pigments must be blended with oil as a medium
Because it is oil as a medium, it is not easy to dry
Generally, it takes one month to air the surface thoroughly
It won't darken when it dries
Will maintain the thickness and glossiness of the pigment layer
Generally, a background color needs to be applied to the canvas
The brushstroke of oil painting is extremely strong
The most outstanding feature of oil painting is its easy to thin and thick brush touch
Oil painting can effectively preserve your brushstrokes while painting
Gouache pigment
Water powder pigment is a type of pigment with relatively large particles,
We need water to mix the paint for painting,
Similar to watercolor features,
But the ductility is not as good as watercolor, and the transparency is not as strong as watercolor
It is easier to dry and draws thicker,
Pigments are prone to cracking on paper
Techniques similar to oil painting and acrylic
At the beginning of coloring, the color saturation is very high and very bright,
But after drying, it will become slightly gray and lighter
If you encounter water after painting, it will dilute the color
Pigments are relatively inexpensive and suitable for beginners to use
It can be drawn on gouache paper and sketch paper,
Not suitable for excessive depiction, with limited techniques
This type is not suitable for long-term painting
It's best to paint it all in one go
If you add strokes later, there will be more obvious marks
Pay attention to the sealing of pigments and maintain sufficient moisture content
