The selection of oil painting for study is an extension of the selection of oil painting for living room to a great extent. But since the study has its own characteristics, it may slightly different from the living room. First, the study is smaller, so the painting you select should be with a proper size. If the size is too large, it may give people a sense of strong oppressive; while too small may not only limit the painting itself, but also make the painting lose its decorative function. Second, you should handle with the two elements of “quiet” and “artistic conception”. The theme of the painting should be quiet rather than activity. The Paris street scene in fashion now is not adapted for the study. Meanwhile, the colors of the painting should be soft and warm which could create an atmosphere of “quiet”. The picture of the painting should have a strong layering effect and going far & stretching effect which could increase the sense of space for the study as well as relax your eyes. As for the subjects of the painting, except the coordination and artistry, it also should have a historical and cultural background in order to upgrade the “artistic conception”. If the study is smaller than 15 square meters, the introduced oil painting is French countryside scene, Thomas garden scene and Venice waterside scene (paintings with typical landscape of the south of Yangtze River for Chinese style decoration) etc. which is combined with the subject of architecture and landscape. If the study is larger than 15 square meters, the highly introduced style is “picture-in-picture” which is perfect match except the high price.
