Everyone's chromatic aberration mainly comes from 1. Racial differences; 2. Regional differences; 3. Cultural differences; 4. Personal experience differences. Beginners of oil painting should know at what stage their color sense is. (If there are not many cross-cultural, cross-ethnic and cross-regional color experiences, the color difference with people around us mainly comes from personal experience. It is necessary to know more about other cultures, national customs and habits, and people's preferences for colors in geographical areas. )
If you want to improve your color vision quickly, the following methods are recommended:
1. Select famous works for color identification: after color identification, call out the colors one by one with oil paints to get the color atlas of the works. Copy a work with the colors in the color atlas. Although it is boring, the color sense improves quickly. Disadvantages: there is no way to form your own color system in a short time. )
2. Choose objects with clear color relationship to sketch: Clear color relationship includes pure color of screen objects (especially main objects); Background (generally refers to interlining) has obvious hue tendency or slightly higher purity, and objects (especially the main objects in the picture) have a clear relationship with the background. Bright color relationship can effectively stimulate beginners' desire and interest in color expression.
3. Choose red, yellow and blue still life to combine: pay attention to the color between the three colors of still life. Proper configuration of sketch objects with strong contrast in color, purity and hue is helpful to understand the taste of color and the color tendency after color interweaving.
4. Practice the shape and color separately: the shape is practiced by drawing a monochrome draft, and the color is practiced by the method in 3 above.
5. On the premise of respecting the correct relationship between objects and colors, strengthen or exaggerate colors: any creation is forbidden to completely copy reality, and even surrealism mostly highlights the tension of the picture through huge frames.
A large number of small color manuscript exercises can also improve the perception of color and control the overall picture. Many beginners don't have a holistic view, which can be solved by practicing small color's draft. (small color's manuscript is relatively short, so it is necessary to simplify the object first and then simplify it, and only draw the big color relationship. )
When drawing small color's manuscripts, sketches or landscapes with the same color tendency are generally the main ones, which is conducive to capturing fleeting color feelings and strengthening color perception and color accuracy.
Small color draft training method:
Small color draft practice, no more than 40 minutes. 40 minutes is the limit of people's attention. If it takes more than 40 minutes, the human brain needs to re-analyze things, which will upset the feeling of doing color exercises quickly. )
You can divide the 50*60 cloth frame into 6 pieces on average with paper tape, and then practice the small color draft quickly with a larger flat-headed pen.
He painted six drafts of small color and six tone sandhi works. Tone sandhi refers to the change and transformation of colors in painting, from one tone to another, which is called tone sandhi. The method of tone sandhi can start with the lightness, warmth, fresh gray and color relationship of colors. )
For example, completely change the color to contrast color and improve the brightness. At a higher stage, the color changes from cold to warm. Only six small color drafts can be trained for each transformation.
