“It was like a profoundly saturated teal … the most saturated natural colour was just pale by comparison,” Roorda said.“I wasn’t a subject for this paper, but I’ve seen olo since, and it’s very striking. You know you’re looking at something very blue-green,” Doyle said.

The researchers said an image of a teal square is the closest colour match to olo. However, this square is not an olo-coloured square. The naked human eye simply cannot see the shade.“If you start with the colour in that picture, and imagine dialling up the saturation further you would get to the teal of real peacock feathers, further still would be a laser in the teal wavelength, and far beyond that is olo, outside the natural space of human colors,” Ng told Al Jazeera.“We’re not going to see olo on any smartphone displays or any TVs any time soon. And this is very, very far beyond VR headset technology,” Ng said, according to a report in the UK’s Guardian newspaper.

Could this technology help people with colour blindness?Berkeley researchers are exploring whether the Oz technology could help people with colour blindness.

“We are now studying the science of boosting the colour dimensionality of signals going from the eye to the brain,” Ng said. “If it proves possible for a colour blind person to see full colour, the next question is whether a person with full colour could be boosted to yet a higher dimension of colour called tetrachromacy.”

This could contain colours beyond the rainbow that would need new names. Ng said that this is part of an ongoing scientific inquiry.the continent endured. Now, she said, some 70 years after independence from colonial masters, is the time to press for change.

“We live in a world where size is often equated with power,” Ogundairo said, adding that the Mercator map feeds tropes that Africa is a country.“It has a damaging impact on the way we make decisions in our everyday lives, on how we make business decisions, the way we dream, and even the way non-Africans view the continent as a tourist destination and an investment destination. It’s the most lingering lie about Africa,” she said.

A heated, centuries-long debate resurfacesCartographers as far back as the early 20th century knew the Mercator projection was problematic.
