What type of colour information do designers want?

In this study we were interested in which type of colour information designers want. We carried out surveys and interviews (with senior designers and brand managers) and the results are summarised below:

We used a card-sorting technique in our interviews to ensure that the participants knew what each of our terms meant.

We found that colour meaning was one of the aspects of colour that designers would like to be able to put their finger on; it was more important that colour trend information in fact! We also looked some existing colour tools and found that none of them really offered the most important information that designers and brand managers want to know about colour. What would be really cool would be a tool that provided accurate information about the meanings that colours have in different cultures and perhaps in different contexts.

The full paper will shortly be published in Color Research and Application.

light that changes colour with your mood

The future of lighting is LEDs and that means more colour. There are many advantages of LED lighting over tungsten or even fluorescent lights not least of which is the opportunity for more colour. I have noticed all of the new buildings on the campus at the University of Leeds are equipped with coloured lighting. The Laidlaw library – and even the new car park – is illuminated at night in an eerie purple glow.

The Syska SmartLight plugs into a standard socket but then can be controlled using the “Syska Rainbow LED” app for your Android or iOS phone or tablet.

I want one. But I am not sure they are on sale in the UK. More details here.

The redder the male, the more successful it is.

According to Joseph Corbo, an associate professor of pathology and immunology at Washington University, the genes affecting red coloration belong to a wider family of genes involved in detoxification. Redness may be a sign of a robust, quality mate who can easily cleanse harmful substances from his body.

“In many bird species, the redder the male, the more successful it is at finding mates,” – Joseph Corbo.

green light may cure your headache

I get migraines. Not often. Just a few times each year. But when I get one I have been known to turn off the lights and go to sleep in my office. I have found that taking a pain killer and then going to sleep is the only way to relieve my symptoms. But a study in the journal Brain suggests that exposure to green light actually has a beneficial effect.

green

In the study 80 percent of subjects reported intensification of headache with exposure to high intensity of light, except green. Surprisingly, the researchers found that exposure to green light reduced pain 20 percent. They also found that the signals generated in the retina for green light are smaller than those signals generated for red and blue light. Researchers are now trying to develop a more affordable light bulb that emits pure narrow-band wavelength of green light and sunglasses that can block out all colours of light except narrow-band green light.

clothes that change colour

Colour-shifting threads that change their hues in response to electrical charges are being developed as part of Google’s Project Jacquard. The technology still has a way to go before it could be in the shops but it gives the potential that your could change the colour of your clothes with the ‘flick of a switch’ rather than buying new ones or even that clothes could change colour with your mood. As if that would be a good thing.

what colour is your passport?

passport colours

Whenever I am travelling to a conference and standing in a line at an airport it seems to me that everyone has either a burgundy passport like me or a red one if the are from USA. It turns out that most passports really are the same colour as this great infographic shows. Well, one of only about four colours so it seems. It’s interesting the way they are grouped; I wonder why Africa tends to use green or black. For the full story see. here.

colour helps you sleep

Light in our natural environment tends to be bluer first thing in the morning and redder at dusk.

Researchers from the University of Manchester looked at the change in light around dawn and dusk to analyse whether colour could be used to determine time of day. They constructed an artificial sky beneath which they placed mice and they then measured the body temperature of the mice for several days and their body temperature was recorded. The highest body temperatures occurred just after night fell when the sky turned a darker blue – indicating that their body clock was working optimally. When just the brightness of the sky was changed, with no change in the colour, the mice became more active before dusk, demonstrating that their body clock wasn’t properly aligned to the day night cycle.

According to Dr Timothy Brown: “This is the first time that we’ve been able to test the theory that colour affects the body clock in mammals. It has always been very hard to separate the change in colour to the change in brightness but using new experimental tools and a psychophysics approach we were successful. What’s exciting about our research is that the same findings can be applied to humans. So in theory colour could be used to manipulate our clock, which could be useful for shift workers or travellers wanting to minimise jet lag.”
