Color-Blind People: Please Read this Question

Questions & Suggestions
1

To those of you who are color-blind to any degree, can you please comment on these two pictures?

  1. Is the first one legible?
  2. Do they look the same to you?

Thanks.

Achromatopsia is very rare, if that’s what you are asking for.

( The two versions are likely to look different anyway to most ‘color blind’ eyes – see under protanopia, deuteranopia, and tritanopia here: http://www.colourblindawareness.org/colour-blindness/types-of-colour-blindness/ )

I know, but that doesn’t mean I don’t care. :smile:

I just re-ordered my questions, to put the most relevant one first.

  1. Is the first one legible?

That’s actually what I really care about, and the reason for the topic. The second question is just curiosity.

@DanThomas there is this App for you smartphone called CVsimulator, that turns your camera into a simulator for color blindness. There you can also check out the different color blind types, protanopia, deuteranopia, and tritanopia
You can set the degree of color blindness from 0-100%.

Works well for me!

I think it’s now called Chromatic Vision Simulator.

It doesn’t appear to work when I use it to look at my monitor. It appears to work OK viewing the “the real world”.

Such a complex search space – the white point of human visual processing is already very variable

( remember https://en.wikipedia.org/wiki/The_dress )

( all primate visual processing is particularly variable it seems – there are some arguments about group adaptive benefits )

and then that gets multiplied by the large (possibly less helpful) variation in the white points of display devices too …

Good luck !!

Yeah thats the one. Well alright… t´was worth a shot :slight_smile:

It was a great idea! It’s cool to know an app like this exists. I’m sure I’ll end up using it from time to time. I’m always interested.

Hmm, better be careful, though.

Girl: “HEY! Quit videoing me!”

Me: “No, seriously, I was just wondering what your outfit might look to someone who’s color blind.”

Girl: “Are you saying that my outfit looks like it was put together by someone who’s color blind?!”

Me: “Just shoot me now, and get it over with…”

:stuck_out_tongue:

Yes, the first one is legible for sure. For me who is pretty color-blind, it includes a blue-like color, white or light grey color and and yellow-like color, on a grey/beige background, per what I can see anyway.

Awesome! Thanks for replying!

First is legible. They look different. The thing about those of us who are color blind is we don’t know what is it we don’t see because we don’t see it. Some colors separate better for us than other colors.

Thanks. The second image is grayscale. I just wondered if that’s what the first one looked like, to you.

I totally understand that! It’s a great mystery in life - how do others perceptions differ from our own? We can never truly know.

I see color in the first one, and gray in the second one. I prefer the first one. How a non-color blind person sees it I assume is different than how I see it.

You can upload a screenshot to Coblis color blindness simulator, and choose different kinds of color blindness to get an idea of what a person with the particular color blindness will see.
