It sounds mad at the thought of you being able to change the colour of your bike at the press of a button, but that's what I've just read on the Cycling Weekly website. Apparently a company called Hope ,have developed a resin that can be impregnated into the carbon weave and at a press of a button will change the colour of your bike. Not everyone's cup of tea granted, but it would look very cool for the fashion conscious :-) :-)
