Some, like the Denver Fire Department use less common colors like all-over white with stripes, gold in Denver's case. Most fire apparatus use retroreflective markings to increase their visibility in poor light; red and white or red and yellow chevrons on the rear are almost universal, and while most choose a more modest and arguably stylish option in simply making existing stripe patters reflective, some, particularly European fire services and especially those in the United Kingdom and in the Netherlands, choose to have very large and prominent markings. Others still, such as the Munich Fire Department have replaced red with similar but more visible colors, such as fluorescent orange.
