Why is white-on-black text mentioned as “accessibility” for this product?

303 views

I was looking at the information recently for a Kindle Paperwhite and I noticed that under “Accessibility Features” it mentions the ability to invert black and white. This was a win for me, because I just like reading white text on a black background. But then I wondered why that’s considered accessibility. I don’t doubt that it is for someone out there, I just wondered what eye/brain function makes this better and more accessible over black text on a white background. Just curious, and Google doesn’t seem to know.

It could be something that colorblind people can see. There are some colour combinations that some colourblind people cannot distinguish. If you write a text of a certain colour with a background of a certain colour, they might be unable to read the text. However, white on black is probably one that they can distinguish, and so it is accessible to those with colour-blindness.
