The farther one stands form a plant,the finer its texture will appear. For that reason,the distance of view must be considered during the textural study of planting design. Color Color results from light peration,absorption,and reflection. Light rays of variable lengths enter a plant leaf to be either absorbed or reflected. If all light rays are absorbed,none are reflected back to the surface。the result is the absence of coloror black. If all rays are refiected back to surface, the rays are a mixture of different color rays,which results in a color hue. Light rays produce red,orange,yellow,green,bulue,and violet colors. Blends of these color rays produce all of the primary,secondary,and tertiary hues we see. Intenseity is a meansurement of the quality of the basic color in the blend.
