20世纪五、六十年代广东水彩画家汤由础的水彩画语言质朴自然,含蓄内敛,不仅表现了纯净明朗的自然本质,而且还蕴藏着宁静怡然的精神气质和蓬勃向上的时代气息等丰富魅力。本文以广东美术馆汤由础画展出色的水彩画作品为例,运用当代水彩画的基本理论和研究方法,分析论述了汤由础如何以质朴而深沉的水彩画风格表现了自然、人与时代这三者的本质。 In the 1950s and 1960s, the watercolor of Tang Yinyu, a watercolorist from Guangdong, was simple and natural, implicit and restrained. It not only showed pure and clear nature, but also filled with the serene charm of calm spirit and vigorous atmosphere. Taking the outstanding works of watercolor painting by Tang You - feng in the Guangdong Art Museum as an example, this paper analyzes the basic theory and research methods of contemporary watercolor and analyzes how Tang Yuxun presented the essence of nature, man and time in simple and deep watercolor style.
