Matters needing attention in complementary color filling
1. Use clean water
After drawing the shape of the green leaves, use a big brush to paint clear water on the inner area of the leaves. The brush should be as close as possible to the edge outlined by the leaves, but don't touch it. If it exceeds the edge, it is difficult to keep the edge fresh when coloring. Add enough water to let the pigment flow freely.
colour
Use No.8 mink hair synthetic round brush to paint the mixed color of new gamboge and permanent dark green or your favorite mixed green along the edge of leaves, try to avoid the middle area, and let the green pigment on the edge gradually flow back to the clear water to create a soft mixing effect.
Apply complementary color
When the paper becomes dull, a layer of complementary red is brushed with No.20 synthetic round head. The effect of Gu Yong Alizarin Red in this picture is better. Synthetic brushes can better control water and color. Minimize brush strokes and color along the shape of the leaf edge in the middle of the leaf. Because the green in the middle of the leaves is brighter than the green at the edge, red can keep the color well and will not become neutral gray because of excessive mixing.
4. Increase the appearance of veins
The nylon brush in the synthetic brush for acrylic painting is stiffer than the watercolor brush, and it is easier to draw natural lines. Start with the largest and most obvious vein, tilt the brush at a certain angle, and then outline the lines with the pen tip.
5. Draw the shape of the vein
Outline the veins and wait for the leaves to dry. Gently draw a touch of color next to each meridian with the No.8 mink hair synthetic round brush to increase the depth. Wipe off the extra thick thread with a clean 20 # mink hair synthetic brush. If necessary, lift the drawing paper obliquely and let the pigments mix naturally. Let it dry.
Reexamine
After painting is dry, recheck the color of the picture. If the color fades, add a coating. Repeat steps 4 and 5. The more coatings, the more vivid the meridians.
