It seems that only recently companies are carrying out what is known as split testing or A/B testing. Put two designs of a web site out and see which does best. Recently one company did just that. They had one web site with a green call-to-action button (as shown above) and another with a yellow call-to-action button. Changing the call-to-action button from green to yellow resulted in a 187.4% increase in conversions to their website. Is there some effect that yellow light could have compared to green? For example, could yellow light make users more impulsive?
According to Erika Dickstein it may be nothing to do with yellow at all but simply to do with the contrast – the yellow stands out better and therefore is more noticeable. Certainly more research is needed in this area.
New regulations – from 20 May 2016 – will see all cigarette packaging in the same drab green colour.colour with other standardised features such as opening mechanism and font, and with 60 per cent of the casing covered by text and images showing how smoking affects your health. The decision was made in Parliament on 15 May last year.
They have also been told to get rid of any misleading information from cigarette packs, and have been prevented from using words such as ‘organic’, ‘natural’ or ‘lite’, which could lead consumers to believe there is a healthy smoking option.
Further information can be found in this article in The Independent.
The images shown above are from a similar scheme in Australia.
The work that has been done has been done in petri dishes in lab however and further studies are needed to see if certain coloured sheets could be effective bug deterrents.

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.
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.
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.
Interesting article by Ian Johnston in The Independent today about consumer colour choices for second-hand cars in the UK. Bucking the recent preference for silver, black and whit, the top 10 list of colour schemes includes green, beige, yellow and gold – colours that we associate with the 70s.

I just saw an interesting article by Kim Lachance Shandrow about how the colour of your office can affect productivity. The article refers to a paper (2007) in Color Research and Application (CRA) by Nancy Kwallek entitled Work week productivity, visual complexity, and individual environmental sensitivity in three offices of different color interiors. The paper suggests that the influences of interior colours on worker productivity were dependent upon individuals’ stimulus screening ability and time of exposure to the interior colours. CRA is a top quality academic journal that is peer reviewed and so I am respectful of the findings.
However, in Kim’s online article there is a lot of stuff that I am highly sceptical about. For example, she writes that “Red … increases the heart rate and blood flow upon sight.” Is this true? Is there really any evidence for this. I have two PhD students working in this area right now and I am far from sure that colour does affect heart rate and, if it does, the effects are probably tiny. And yet we can read statements like this all over the internet as if it is a fact beyond doubt. Other things she says that I take with a pinch of salt is that “green does not cause eye fatigue” and that “yellow triggers innovation.” Don’t get me wrong – I am very interested in how colour can be used to affect us emotionally, psychologically and behaviourally; it’s just there is a danger that if some things are said often enough (such as red increases your blood pressure or heart rate) then people start believing them even though there may be little evidence.
That said, you might find the infographic fun and it is well done. See the original and full article here.
Recently both coca-cola and pepsi have introduced interesting green packaging. To see what Chris Arnold, author of Ethical Marketing & The New Consumer, thinks about this click here.
About three years ago I posted about the question of why leaves are green. In this I postulated as to why chlorophyll (the green stuff in leaves) should be green; after all, this means that it only absorbing some of the wavelengths in the visible spectrum. In fact, I argued that it would be better if plants were black, absorbing all of the wavelengths in the visible spectrum. Now, someone on co.design is suggesting just that – that green plants absorb only about 2% of the possible energy and that scientists are thinking of turning them black. Presumably this would save the world because plants would be more efficient at converting harmful greenhouse gasses into oxygen. There’s catch though, apparently. If you make the plants black they get too hot and overheat resulting in cell damage. Actually, I also suggested this might be the case in my original article in 2011. Looks like black plants won’t save the world. They won’t even save themselves.
There’s nothing wrong with black carrots though – see here.
The oil giant BP has again failed in its long-running bid to trademark the colour green in Australia.
The intellectual property watchdog, IP Australia, found BP was unable to show “convincing evidence” that it was indelibly linked in the average petrol consumer’s mind to the dark green shade known as Pantone 348C, a spokeswoman for the government agency said.
BP first tried to register a trademark for the colour in 1991, and until 2013 fought legal battles against another corporate titan, Woolworths, to stake its claim to the colour as the dominant shade for its service stations.
