As stated earlier in this chapter, some designers have the requisite computer skills to develop color renderings using various programs—among many others are Adobe Illustrator and Adobe Photoshop. The two renderings in Figure 15—27 were developed using Adobe Illustrator. The drawing on the right uses greenish tints of blues and browns. The drawing on the left uses various values of yellows, tans, and browns. Both were developed as “analogous color schemes.” Rather than using colors from most of the color spectrum (reds, oranges, yellows, greens, blues, and violets), each of these renderings focuses on a small range of colors that are closely related. Accent colors include (1) white, for texture on ground cover and water, as a well as for branches in the evergreen shrubs, and (2) rust, for texture on the ornamental tree and for banding in the circular patio. A variety of values was used for peppering the lawn area and some of the ornamental trees.
