A sign with blue lettering on a green background is considered inappropriate for human use because these colors are too similar in wavelength and can be difficult for many people to distinguish, especially those with color vision deficiencies. This can make the text hard to read and the sign ineffective. High-pitched fire alarms, on the other hand, are designed to be easily heard and grab attention quickly, making them appropriate for their intended use.
