Dobrovolsky works with a palette knife and oil on a colored background. Developed a technique of contrasting colors. The artist creates pictures using the "pictorial mosaic" technique, and this gives the artist the opportunity to convey iridescent light in dozens and hundreds of different shades - "valers" of color. Dmitry uses an interesting combination of colors that contrast with each other, and with this he achieves an amazing color harmony. The main plot of practically all of his paintings is based on color, on the level of feelings.
