The Colour Group's Turner Medal was presented to Adriana, daughter of Carlos Cruz-Diez, at a ceremony in the Great Hall at City University. Carlos could not be present but there was a live video link to him in Panama (ABOVE). He was introduced by artist Philip O'Reilly (BELOW LEFT) and then the audiences viewed a film (BOTTOM LEFT) in which Cruz-Diez explained his life's work and philosophy. This was followed by a question and answer session before the presentation of the medal by Chairman Valérie Bonnardel (BELOW RIGHT). The evening finished with a reception (BOTTOM RIGHT) for gossip and networking.

ICD clockINTERNATIONAL DAY OF
COLOUR CLOCK

For those of you who like clocks based on colour circles, as we do - see ours, top right - you might like the two versions of clocks that celebrate the IDC from the Color Association of Taiwan. Of course, none of these are, strictly speaking, clocks but are only time pieces. A clock should have a mechanism to strike the hours, etc. whilst a time piece merely shows the time. Perhaps we should work on this.

red/blue clockCOLOUR OF DAYLIGHT SETS INTERNAL CLOCK

It has been suspected for years that the colour of daylight, e.g. the reddening at dusk, might set your internal clock to "sleepy-time" but firm evidence has been wanting. Now a study on mice suggests that this might be so. For humans it could mean that reddish light makes you sleepy and blue light makes you feel awake.

SAINSBURY'S CHANGE SWEET WRAPPERS FOR COLOUR BLIND ALLERGY SUFFERERS Treats

David Dunbar of the Colour Blind Awareness organisation has persuaded Sainsbury's to change the wrappers of their Chocolate Treats. He has a son with a nut allergy and was worried that colour blind people with allergies might pick a potentially dangerous sweet. Sainsbury's said it would put allergy warnings on the wrappers themselves.

SECOND TURNER MEDALIST DIES

Albert Irvion Albert Irvin OBE was the CG(GB)'s second Turner Medalist. The medal was awarded in 2000 and it is reported he died 26 March aged 92. Irvin was an abstract artist who won recognition relatively late, not getting his first solo show until he was nearing 40. One of many obituaries may be seen in the Times or The Guardian.

DULUX COLOUR OF THE YEAR AT ELTHAMEltham

Ever been to Eltham Palace? It's a wonderful example of Art Deco and style created in 1936 by the famous jet-set couple Stephen and Virginia Courtauld. Colour Group member Janet Best, who is a colourist, reports that several rooms at Eltham have been refurbished to revive the stylish glamour of the original and she noted the dominant colour was of Copper Orange, the Dulux Colour of 2015. So Eltham has style beyond the trend.

SPRING INTO GOOGLEGoogle Spring heading

Whilst the Colour Group (GB) was celebrating International Colour Day on the equinox, in India, Google was celebrating the Iranian (Persian) New Year by changing from the usual Google to the spring version with flowers, colours and insects as seen above. When your mouse moved over the word Google, it read Navroz Mubarak. wishing you a Happy New Year.

HOT SPRING COLORS

dress colors

Last Autumn New York Fashion Week promised the hot colours for Spring 2015 would be "Lemon Yellow, White, Sky Blue & More" whilst Pantone chose the colour for 2015 as marsala. Marsala is a Sicilian red fortified wine. Most popular in the UK is the sweet version used for making zabaione. Now Spring is just about arriving so for those of us who are stuck in the colour lab and don't get out much, can you tell us which is winning - the hot colours or the earthy red? The tart lemon or the sweet nectar?

NANO-COLOUR?

lizard and chameleon

So you thought lizards were coloured by chromophore cells and that chameleons changed colour by expanding or contracting these cells. Half right. A group from Michel C. Milinkovitch's lab in Geneva have been studying these features of colour and two years ago reported on lizards. Combining Physics and Biology techniques (histology, optics, mass spectrometry, UV/Raman spectroscopy, mathematical modeling), they showed that the extensive variation of skin color and patterns in Phelsuma lizards (TOP PICTURE) is generated by precise co-localization of interacting pigmentary and nano-structural elements. And three days ago the group reported that chameleons (BOTTOM PICTURE) shift colour through active tuning of a lattice of guanine nanocrystals within a superficial thick layer of dermal iridophores. In addition, they showed that a deeper population of iridophores with larger crystals protect chameleons from excessive exposure to solar radiations by reflecting a large proportion of the sunlight power, especially in the near-infrared range.
If you are not into nano-crystals go to the lab's web pages and look at the videos of chameleons changing colour. You can get the fuller theory there too if you are geeky about this kind of thing.

Prof JANOS SCHANDA

Janos Schanda

CIE (Commission Internationale de l'Eclairage) reported today that Prof Schanda died yesterday. Janos, as he was known to everybody, was a prominent figure in CIE business and vision research. He received many honours one of which was the Colour Group's Newton Medal in 2010. You can see some photographs of Janos at the Newton Medal presentation in the album for March 2010 in the Colour Group Photo Albums (under the Miscellaneous tab above).

LIGHT PIPES IN THE RETINA

The BBC News web pages report work done by Dr Erez Ribak from Technion, the Israel Institute of Technology. The finds are claimed to show that Mullers cells in the retina act like 'colour-sensitive' light pipes that help the eye discriminate colour. As all Colour Group members know, colour is more a mental construct than a property of a class of retinal cells, so you would be right to think the report is simplified. Have a look and judge for yourself.

THAT DRESSTHE dress

The World seems to be going mad about a certain dress. In case you missed the fuss (is this possible?) get the background and a reasoned piece with the links below on why there is (was) a problem:


In addition to the links above, another Colour Group member has taken up The Dress challenge and offers a different interpretation for the differences of opinion about the colour of the bands on the dress. For the moment, it seems, you pays your money and takes your choice of explanation. Of course, this all bodes well for those working in visual science - there could be decades of research projects on colour-contrast of dresses, chromatic adaptation and so on. It only remains to convince the fashion industry that all this is of vital importance..
animated dress pattern

Perhaps colour contrast images like these on the left based on the dress pattern are a way to go for the would-be vision scientist.
