“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.Windram said success would depend on the cause of colourblindness in individuals. Deuteranomaly, which causes decreased sensitivity to green light, is the most common form of colour blindness.

“In this case, a miniaturised version of this technology could theoretically be used to correct this by directly stimulating the cones when the correct colour of light hits them,” Windram said.

Windram pointed out that publicity materials for the research show images of the Oz experiment on a highly stabilised table.“The World Bank Group is committed to ensuring accurate representation of all people, on all platforms,” a spokesperson told Al Jazeera.

Progress is slow but steady, Ogundairo of Africa No Filter said. Prominent organisations changing their stances means a universal pivot is possible, she said. Yet, there’s much more work to be done by Africans, she added.Just as Mercator painted an image that prominently represented his part of the world, Africans, too, need to lead the way in pushing for what they want, Ogundairo said. One missing factor is that Africans have not insisted enough on change, in her view. It’s why her campaign is also urging African countries and the African Union to be particular about how they are represented on the map.

“It’s always going to start with us,” Ogundairo said. “Unless you learn to tell your story, someone else will tell it for you. We need to say, regardless of why they choose to do whatever it is they did, we see the truth. This is the story we want to tell now. This is how we want to show up visually on a map.”rkiye is calling for action – not words. History will judge those who remain silent in the face of genocide.
