Parents in Koskullskulle, Sweden, should pack up their young children's colorful, patterned clothing, because polka-dots and stripes are no longer allowed to be worn at the town's preschool, TheLocal.com reported.

The ban was put into effect because an employee at the school suffers from migraine headaches that are triggered by looking at multi-colored garments.

“It’s a pity for the employee and as a result I’ve tried to create an appropriate work environment," the pre-school's principal, Maj Norberg, told the Norrländska Socialdemokraten newspaper. "The person in question has a right to be able to work.”

Some parents and politicians aren't as accepting.

“I have a hard time believing that they have a right to make this sort of demand,” Ulf Eriksson, head of the National Association of Homes and Schools, told TheLocal.com.

Children who come to school in northern Sweden with “inappropriate” clothes must change into monochrome outfits, parents told TheLocal.com.

Migraine specialist Professor Carl Dahlöf said it is possible for certain patterns to cause the blinding headaches.
