Mainly lies in the difference in shaping effects, materials, characteristics and strokes when painting
1. Create different effects when painting: crayons are not likely to be blurred by water, and they will have a soft and casual feeling when drawn. And the effect of drawing with different paper crayons will be different.
2. Different materials and characteristics: Oil pastels are not afraid of water, high temperature resistant, and relatively stable. The crayon will melt when exposed to high temperature, and the color is very dark, easy to dry and crack.
3. The strokes of oil pastels are slightly thinner than crayons. Oil pastels have the subtle effects required for mixing and layering, but crayons do not.
The freshness and color preservation time of colored crayon paintings last longer than oil paintings or watercolor paintings. They won't fade like oil paintings or get damp like watercolors. The beauty of crayons lies primarily in their soft, velvety surface, which imparts a color harmony, depth and atmosphere unattainable to his method. Colored crayons are especially useful for drawing portraits, still lifes, and some landscapes.
The oil pastel feels fine and smooth, has good spreadability, and has color stacking and color mixing performance. It can fully display the effect of oil painting and meet the difficulty requirements of various painting skills.
