Determination of Shape and Color Relationship in the Visual Perception of the Leaves of Some Evergreen Trees

In planting design, the leaves have the most important contribution of plant species on texture and color effects. Leaves are used as a design element in the space according to design principles and their evaluations according to visual perception will create more effective and successful results in planting designs. In this study, it was aimed to determine the relationship between shape and color in the visual perception of the leaves of evergreen broad-leaved trees at Akdeniz University campus in Antalya city center. For this purpose, photographs of 16 tree species in January were used as study material. In this respect, a questionnaire including the photographs of leaves of 16 tree species and the questions about determining some personal characteristics of the users and semantic differentiation technique for the semantic evaluation of the leaves by the users were used. As a result of the study, the relationship between the visual perception of beautiful and impressive feature of leaves, leaf shape, leaf color, leaf shape and color harmony was found to be statistically significant. In addition, it was determined that the age and gender characteristics of the users significantly affected the visual perception of the leaves. As a result, in evergreen tree species, light green color oval, elliptic and single leaves were found to be visually well perceived. In plant designs, it should be considered that leaf color and shape relations are effective in the visual perception of evergreen trees' leaves
