I have worked in colour for pretty much all my working life. Though it has led to a rewarding and stimulating career (with a little bit of success) and though my passion for colour has never waned, I do sometimes wonder if i could have put my life to something more useful. Not that colour is not useful, far from it, but what I mean is something that could save lives. For example, perhaps I could have become a researcher looking into a cure for cancer. Compared with research like that, doesn’t colour sometimes seem frivolous and secondary?

So my Friday morning today was just cheered up a little when I came across an article in the Grundig about how colour-changing technology could revolutionise the medical industry. Apparently, 1.3 million people die each year because of unsafe injections, making the humble injection the most dangerous clinical procedure in the world. Part of the problem is that syringes are sometimes accidentally reused without sterilisation.

In response to this serious issue, David Swann at the University of Huddersfield – just down the road from where I work – developed a “behaviour-changing syringe” that warns when the needle is unsafe. Once opened the syringe turns bright red within sixty seconds. It’s not even expense. Apparently a standard syringe costs 2.5 pence whereas the “behaviour-changing syringe” costs 2.65 pence.
