Images of 17 million colours have no two pixels the same

Hungarian programmer turned artist József Fejes has created a computer program that will generate images using nearly 17 million different colours with no two pixels the same colour!

He created the image as part of the allRGB project where the object is to “create images with one pixel for every RGB color (16777216); not one color missing, and not one color twice.” Some people have accomplished this editting well known images such as the Mona Lisa or the classic photo of Einstein with his tongue out.

Fejes however wrote a code and let that do the generating and some of the outcomes are stunning. Some appear floral, like watercolours, and he calls them “rainbow smoke”.

At first I didn’t really know if it was going to end up looking beautiful or not, it was just an interesting programming challenge for me,” he says. “I was very surprised at how beautiful it turned out to be.

In the competition they could use as many as 16,777,216 colours – the highest number possible with 24-bit RGB technology. This is because the colour of any RGB pixel is determined by how much red, green and blue light it contains. In 24-bit colour, each of these three components has an intensity value from 0 to 255 (256 x 256 x 256 = 16,777,216).

New Scientist explains how his code works: “The program works by automatically plotting coloured pixels according to how similar they are in hue and brightness. In some images, a colour is picked at random and then placed in the most suitable location, before another random colour is selected and placed. In others – the “rainbow smoke” examples – the program goes through each colour group in sequence, so all the reds are placed, then the oranges and so on.

The images in this post have been compressed of course and do not contain as many colours as the originals which have a resolution of 4096 x 4096. The screen you use will also affect how you see these images.

And if you thought to yourself “whatever I bet the human eye can’t even distinguish that many colours” you’d be wrong. The eye can not only perceive all of these colours but also a wide range of additional colours outside RGB’s limited palette. Pretty mind blowing huh?
