Research at Delft University in The Netherlands shows that background colors affect the attractiveness of vegetables.

Five different vegetables were presented on four different background colors. The researchers found that their attractiveness varied with the backgrounds. But there's no rule of thumb: quite different backgrounds proved optimal for the various vegetables. The outcomes suggest that it will be difficult to find a background color on which a large number of vegetables can be presented in the best possible way.

It's interesting to note that many 'experts' on color fail to define what color really is. Could it be that they don't know? 

"Newton himself, who actually introduced the word “spectrum” into the English language to refer to the range of possible colors, eventually dismissed the idea that colors are literally contained in the light. “For the Rays, to speak properly, are not coloured. In them there is nothing else than a certain Power and Disposition to stir up a Sensation of this or that Colour.” Three hundred years on, what and where colors actually are remains a mystery."

If you're ready for some mind boggling ideas about color, here are more thoughts on the subject, by Riccardo Manzotti, philosopher, psychologist, and artificial intelligence scholar.

It seems we're headed towards a future of mechanical colors. Most of the colors that we are used to, particularly paint colors, are produced in chemical processes. Or we use natural materials that have an innate color, such as earth colors. But in the last few weeks alone, three breakthroughs have been reported on the production of non-chemical colors:
Color-changing graphene bubbles to create ‘mechanical pixels’
Changing the color of your clothes on a whim
Bright colors by nanotechnology

Vermeer's Milkmaid in transplanted colors:

Did you guess that the bottom left image is Vermeer's 'real' Milkmaid? A simple survey shows that many people pick another one as the 'real' image. 

 The colors of these Milkmaids have been transplanted from the following pictures:
Portrait of Raden Syarif Bustaman Saleh, by Friedrich Carl Albert Schreuel in 1840
Portrait of Maria Theresia of Austria, by Jean-Etienne Liotard in 1747
Portrait of Isaac de Bruijn, by Jan Veth in 1922
The Milkmaid, by Johannes Vermeer in 1658

Below you can produce your own color transplant with an interactive version of the Milkmaid.

Pantone recently released a new app for iOS, called Pantone Studio, and it's pretty cool. It has everything you would expect, like an overview of all the Pantone color collections, and data on individual colors. Off course you can also save your own palettes. But there's more. You can load an image and extract colors from it. There are more apps doing the same. But most of them depend on an algorithm that automatically turns image colors into paint. Problem is, a photo of a blue wall is not the same as a pot of blue paint, because each individual photo has its own individual lighting situation, which hugely affects the colors. The Pantone app doesn't solve that problem, but works around it by allowing you to pick your own colors in the image. So you can also pick a color of the air, your skin or a leaf. It's a more impressionistic approach, which leads to less worrying whether or not the color you get exactly matches the color of the object in the image.
Secondly, the app can even find new, matching palettes for you in the vast collection of Colourlovers. is a website that has collected a huge amount of hand made color palettes. 
All in all, Pantone did a really good job with this app. You can use it for free with a limited number of colors. Full access to all the Pantone colors and references requires a paid subscription.

One of the most iconic paintings hailing from the Dutch Golden Age is Vermeer's Milkmaid. In 1658 he depicted a maid with clothes and surroundings in very distinct colors. How important are the colors to this image? What if we could transplant the colors of other renowned pictures onto the Milkmaid?

Actually our technology, at Colorjinn, allows us to do exactly that. So here it is:
