My Belle Cosmetics is a large business that has sales well ahead of any other regional cosmetics firm. As an organization, it is very sensitive to color, because it introduces new color lines in its products every fall and spring. The company has recently begun using technology to electronically show in-store customers how they appear in different shades of cosmetics without requiring them to actually apply the cosmetics.

a. Design and draw a representation of a display screen that can be used by sales clerks at a counter to try many shades of lipstick and makeup on an individual customer very quickly and with a high degree of accuracy. Input from customers should be their hair color, the color of their favorite clothing, and their typical environmental lighting (fluorescent, incandescent, outdoor, and so on).

b. Design and draw a representation of a display screen that is equivalent to the one in Problem 7a but that vividly demonstrates to decision makers in My Belle how color improves the understandability of the screen.

c. One of the affiliates My Belle has on the Web is a large department store chain. In a paragraph, describe how the display screen in Problem 7a can be altered so that an individual can use it and My Belle can put it on the department store’s ecommerce site to attract customers.
