xi End-of-Chapter Content End-of-chapter material provides an oppor- tunity for review and application of concepts. A concise Summary provides an additional review tool and reinforces key learning objec- tives. This helps you focus on important concepts presented in the text. Activities extend your learning and help you apply knowledge. Review Questions allow you to demonstrate knowledge, identification, and comprehension of chapter material. ASE-Type Questions help you prepare for the types of questions encountered on the ASE certification tests. 750 Section 5 Refinishing Copyright Goodheart-Willcox Co., Inc.. Summary • The light source a color is viewed under determines the appearance of the color. Therefore, color should be evaluated in natural light rather than artificial light. • The color of an object is determined by the wavelengths of the light reflected by the object. • Red, orange, yellow, green, blue, and violet are the six visible hues in the spectrum. • Colors can be viewed either straight on or from an angle. • Even when paint code numbers match, the refinish paint often does not match the paint color. • Hue is the name of the color. • Value is the lightness or darkness of a color. • Chroma is the intensity or brilliance of a hue. • The three qualities of color are visually displayed in a color tree. • Use the hue portion of the color tree, which is called the color wheel, when describing color differences. • A comparison panel is used to check for color match. • A letdown panel is created to color match a tricoat. • Locating two different colors on the color tree will show the painter exactly how the colors are different. This is called plotting a color. • A spectrophotometer is an electronic device that determines the color of a vehicle by measuring light intensity reflected from the sample. • Color can be adjusted by tinting. Activities 1. Make a color wheel. On a single sheet of blank paper, use color pencils, markers, or crayons to depict a color wheel that contains the eight primary and secondary hues used in automotive refinishing. 2. Make a chart listing the reasons why colors do not match. Participate in a classroom discussion on what can be done to remedy a where colors do not match even when the factory color formula. 3. Tinting involves changing the color of refinish paint by adding or subtracting Prepare a brief five-minute presentation on additive or subtractive tinting. Be sure to include information on undesirable such as metamerism, and how metallic flakes can darken a color.the Review Questions Answer the following questions using the information provided in the chapter. 1. The difference between colors should be evaluated in _____ light rather than artificial light. 2. A color will always look the same under fluorescent light and under sunlight. True or False? 3. Visible light contains all the colors: red, green, blue, orange, yellow, violet. True or False? 4. Black pigment _____ all light wavelengths, while white pigment _____ all white wavelengths. 5. The color of an object is determined by the wavelengths of light reflected by the object. If that is so, the paint on a green vehicle absorbs violet, blue, yellow, orange, and red wavelengths, but it reflects the green wavelength. True or False? 6. List the two views described by the term “pitch.” 7. A metallic color is more intense (chroma) than a solid color. True or False? 8. The orientation of metallic flakes determines the _____ or _____ of a color. 9. Which type of automotive paint has a pearl midcoat? 10. The way we see color is entirely dependent on the light source it is viewed under. True or False? 11. Men are more likely to be color-blind than women. True or False? 12. The primary hues are red, yellow, and blue. Automotive refinishers use a fourth hue. What is it? 13. The color of a paint is also known as _____. 14. A high value hue is dark. True or False? 15. Intensity, brilliance, saturation, dullness, or vividness, clean/dirty, can all be used to describe this quality of color. 16. Adding metallic to a color will do what to chroma? 17. A red can be described as too green. True or False? 18. The subtle presence of an adjacent hue in a color is called _____. 19. Two vehicles with the same paint code may have colors that are slightly different. True or False? 20. Explain how to make a letdown What is a 22. Spraying a metallic paint wet will make the color look _____. 23.
