In 1935 the K6 Red Phone Box (kiosk number six) was designed to commemorate the silver jubilee of King George V. K6 was the first red phone box to be used extensively outside of London, and many thousands were deployed in virtually every town and city, replacing most of the existing kiosks and establishing thousands of new sites. It has become a British icon, although it was not universally loved at the start. The red colour caused particular local difficulties and there were many requests for less visible colours. The red that is now much loved was then anything but, and the Post Office was forced into allowing a less strident grey with red glazing bars scheme for areas of natural and architectural beauty. Ironically, some of these areas that have preserved their telephone boxes have now painted them red.
