Tekken 8's 'Colorblind' Mode Is Causing Migraines, Vertigo, and Debate

An anonymous reader quotes a report from Ars Technica: Modern fighting games have come quite a long way from their origins in providing accessibility options. Street Fighter 6 has audio cues that can convey distance, height, health, and other crucial data to visually impaired players. King of Fighters 15 allows for setting the contrast levels between player characters and background. Competitors like BrolyLegs and numerous hardware hackers have taken the seemingly inhospitable genre even further. Tekken 8, due later this month, seems to aim even higher, offering a number of color vision options in its settings. This includes an unofficially monikered 'colorblind mode,' with black-and-white and detail-diminished backgrounds and characters' flattened shapes filled in with either horizontal or vertical striped lines. But what started out as excitement in the fighting game and accessibility communities about this offering has shifted into warnings about the potential for migraines, vertigo, or even seizures.

You can see the mode in action in the Windows demo or in a YouTube video shared by Gatterall -- which, of course, you should not view if you believe yourself susceptible to issues with strobing images. Gatterall's enthusiasm for Tekken 8's take on colorblind accessibility ('Literally no game has done this') drew comment from Katsuhiro Harada, head of the Tekken games for developer and publisher Bandai Namco, on X (formerly Twitter). Harada stated that he had developed and tested 'an accessibility version' of Tekken 7, which was never shipped or sold. Harada states that those 'studies' made it into Tekken 8.

Not everybody in game accessibility circles was excited to see the new offerings, especially when it was shared directly with them by excited followers. Morgan Baker, game-accessibility lead at Electronic Arts, asked followers to 'Please stop tagging me in the Tekken 8 'colorblind' stripe filters.' The scenes had 'already induced an aura migraine,' Baker wrote, and she could not 'afford to get another one right now.' Accessibility consultant Ian Hamilton reposted a number of people citing migraines, nausea, or seizure concerns while also decrying the general nature of colorblind 'filters' as an engineering-based approach to a broader design challenge. He added in the thread that shipping a game that contained a potentially seizure-inducing mode could result in people inadvertently discovering their susceptibility, similar to an infamous 1997 episode of the Pokemon TV series. Baker and Hamilton also noted problems with such videos automatically playing on sites like X/Twitter. 'Patterns of lines moving on a screen creates a contiguous area of high-frequency flashing, like an invisible strobe,' explained James Berg, accessibility project manager at Xbox Game Studios. 'Human meat-motors aren't big fans of that.' People typically start to notice 'flicker fusion frequency' at around 40 frames per second, notes Ars.

Tekken's Harada responded by saying a 'very few' number of people misunderstood what his team was trying to do with this mode. There are multiple options, not just one colorblind mode, Harada wrote, along with brightness adjustments for effects and other elements.

'These color vision options are a rare part of the fighting game genre, but they are still being researched and we intend to expand on them in the future,' Harada wrote. Developers 'have been working with several research institutes and communities to develop this option,' even before the unsold 'accessibility version of Tekken 7,' added Harada.
