11/13/2017 In the early 1970s, Ward LaFrance created what was probably the most controversial issue ever to hit the apparatus field. By aggressively marketing a new color for fire apparatus, lime green, as being more visible and therefore safer, a wedge was driven into the fire service. Traditionalists stood behind the old standard red, while "progressive" fire service personnel preached the advantages of the new color. At one point, there were actually more apparatus being delivered in the new color than the traditional red. Many fire departments, both large and small, switched to the new color. http://www.firehouse.com/magazine/american/apparatus.html 23

11/13/2017 For years, fire trucks have been painted red, hence the name “fire-truck red.” But several years ago it was discovered that this red hue is hard to see at dawn and dusk when there is little light. Today, yellow-green is used for fire trucks and hydrants because it can be seen from farthest awar, regardless of the light and time of day. Years from now when school children ask what color fire trucks are, they will answer “yellow-green.” Contemporary Color Theory and Use: Theory and Use Steven Bleicher, Cengage Learning, 2004; page 42 24

11/13/2017 Many fire departments, both large and small, switched to the new color. But after about a decade, departments began to switch back to red. Many apparatus were repainted. Virtually every large department that had gone to the new color returned to red. Currently, few new apparatus are being delivered that are painted lime green. http://www.firehouse.com/magazine/american/apparatus.html  = wavelength 1   = frequency c = speed of light c =      1/  ========================================= blackbody radiation, photoelectric effect  E = E photon = h  31
