The symbol / logo displayed below has been designed to be applied to the packaging of emergency mobile phones for mountaineers to warn them of very low temperatures. Alongside each of the designs explain your views on the design. Thermochromic inks are inks that change colour according to temperature. As the temperature falls to dangerous levels the colour of the ink on the emergency mobile phone packaging could change. This would be a visual warning.

Produce your own design for an emergency mobile phone symbol - for mountaineers to warn of extreme cold. In box ‘A’ draw a rough sketch of your basic idea and in box ‘B’ draw a colour rendered final design. Use space ‘C’ to add notes explaining your design and colour scheme.
