Study On Artistic Expression Of Coarse Grained Rock Color Painting

The biggest feature of modern rock color painting is the coarse grain,and the biggest feature of the coarse grain is its materiality.The materiality of coarse particles is mainly reflected in the texture,picture texture and color visual effect.The texture of coarse particles is mainly manifested as the crystal clear coarse particles,which can be refracted in the light.It highlights the material language of mineral pigments and emphasizes that this unique texture is not found in other kinds of paintings.The larger the mesh number of coarse particle mineral pigment color is not easy to change significantly because of the concentration of glue,and the smaller the mesh number of coarse particle mineral pigment is more susceptible to the influence of the concentration of glue,the thicker the glue,the darker the color,the lighter the glue,the closer to the primary color.Such as bean green,bean green these special colors need to be purified,the color is closer to the primary color of the mine,and the gelatin solution drawn directly has a large difference with the primary color,the color of the impurity layer can be clearly seen in the color,in use can also be reasonable use of the mine according to its special characteristics.The main feature of modern rock painting is the fusion and collision between colors,especially for coarse grain rock painting.Through the mutual penetration and coverage between the coarse and fine particles of mineral pigments,subtle and obscure color changes are formed,which is the unique characteristic of modern rock color painting and other pigments,and all these need to achieve such rich color changes through color stacking.The texture of rock color painting exists in many forms,but usually coarse grain mineral search can give the viewer more intense stimulation of the sensory system,produce more profound memories.Usually,coarse grain rock color painting will have a certain thickness of the picture,and natural mineral pigments will refract the light under the spot lamp to produce a unique luster,which makes rock color unique charm.Almost all rock color painting creators will skillfully use texture in the process of painting.Finally,the author’s artistic expression research on coarse grained rock color painting is further elaborated with examples to prove the previous research.
