Yellow and orange colors are considered by most Amish communities as being too flashy and are rarely used in any way throughout the community. In fact, if you've ever been to an Amish community, you'll notice that their black buggies have a bright orange yield sign on the back of them. This was something that was imposed onto the Amish by the government that said the buggies needed to be visible to cars at night for the safety of both drivers. Many communities fought the use of the brightly colored signs due to their religious beliefs that prohibit the use of orange or brighter colors.
