@marcamos it’s wonderful, I’ve known it for some time too

@marcamos Bookmarking this!

And maybe I can offer another in exchange. I use COBLIS for graphics testing: https://www.color-blindness.com/coblis-color-blindness-simulator/

It's geared to simulating colorblindness for whole images. Both might be useful for different reasons.

@marcamos This is really cool. I'm going to send it to my color blind family members.

@marcamos That's a good one - Lots of details on different user types. I think my favourite for formulating (rather than just checking) is still https://colorable.jxnblk.com/

@marcamos this is really cool. Thanks for sharing!

@marcamos Kind of disagree for the red text on black, though. I find it very hard to see.

@marcamos a friend of mine built https://play.google.com/store/apps/details?id=net.inclem.colourblind which use the android camera to simulate a few conditions. it's open source, too https://github.com/inclement/colour-blind-camera

@marcamos Thanks for sharing! This will come in very handy.

@marcamos ooo I'll definitely be using this

@marcamos Wow nice, dodn't know that. Thanks a lot!

@marcamos what a great page! And kudos for this paragraph on the bottom left!

@marcamos this is nice. It’d be useful to have something like this for a design system, so you can easily test whether multiple button types (e.g. primary, secondary, etc) have contrast with each other, even if they pass when they’re standalone.

@marcamos That is awesome.

@marcamos But those 56 will boost to another 56, and they to another, and I don't find the original Dune quote to finish the toot with its full inspirational potential.

@marcamos One nice trick is that you can paste your rgb(a) definitions in there (eg. rgba(49,53,67,.95)) and it'll convert them to hex (stripping the alpha part, but that's understandable)

@marcamos You might discover some other useful on https://canwe.dev (I maintain it).

@marcamos holy shit, this is exactly what I wanted when I was looking for ways to help make my own site more accessible, thank you. Tools like this are so useful in helping devs understand how to make the web more accessible.

@marcamos here’s another great one for anyone else doing data visualisation and wanting to test palettes for being colourblind safe 😊 https://gka.github.io/palettes/ #rstats #dataviz

@marcamos this tool is in my faves since i discovered it last year !

@marcamos My Wikipedia signature scored AAA on everything except direct sunlight, where it got AA

@marcamos this is SUPER useful! Thanks!

@marcamos thank you! This is amazing!

@marcamos *trying to create text invisible to one of my partners* :>

@marcamos
like to see that my current color combination works (AA rating only in direct sunlight )

@marcamos this is really cool. Thank you for sharing it!

@marcamos
Thank you for this.

The moment I saw this, I thought "Crap, there's one customer with links in the footer of their login page that I bet wouldn't do well here."

Yeah. 100% fail.

Opened an issue, and am adjusting the colors to pass at least most of them.

@marcamos I actually love this little detail as well, I hope they don't change it

@marcamos 61! :)

@marcamos Das ist cool.

@marcamos

Pretty interesting tool.
But I wouldn't consider this a "fail":

@marcamos a really great range of eye issues represented there though nothing for my issue, being unable to read light text on a dark background, which seems to be due to astigmatism

@marcamos what an awesome tool. #color #graphicdesign

@marcamos What?! Awesome! Thanks for the heads up. 😍

@marcamos Huh, interesting. I tried to create the "worst case scenario" for Protanomaly and it somehow scores *better* than Regular Vision there? I Guess my naive intuition about how color blindness works is way off (or the tool is).

@marcamos +1 from an #actuallyautistic person who can see those monstrous colour palettes, but genuinely wishes she couldn’t.

@marcamos Maybe of interest @dogwonder

@marcamos @tcit Contrast Ratio 15.46:1 / WCAG Grading AAA on my blog without even thinking about it :p

@marcamos https://whocanuse.com, a tool to view colors as seen by people with different vision abilities #accessibility

@marcamos thanks for sharing. Looks like a very useful tool.

@marcamos 56 people, but it looks like I was the 250+th person to boost it. So yeah: good find and great work getting it out there!

LB: if anyone wants to extend https://quietmisdreavus.github.io/mkcolor/ with the color-blindness math that that site links to, that would be cool 👀

@marcamos this is FANTASTIC

@marcamos I'm disappointed that sir doesn't show what it looks like with astigmatism.

@marcamos
Oh thank you! I have actually been looking for something exactly like that

@marcamos As one of the 0.05% of the population (apparently) with complete Achromatopsia, it does feel nice to be included!

@Meyerweb you might like this

@marcamos I had no clue something like this existed, but that's awesome. Not useful for me specifically but there's clearly a use case it meets.

@marcamos omg, the favicon even updates as the colors do

@marcamos Wow

@marcamos this is awesome! I'm terrible a picking contrasting colours and need this tool in my life. Thanks for sharing! 😀

@marcamos @beno @ohnojono

@marcamos and this is how I see the World http://visualsnowsyndrome.com

@marcamos Cool page. One often overlooked issue it doesn't take into account, though, is that e.g. dark red text among black text doesn't particularly stand out for protanomalous people like me, even though red on white isn't a problem per se. #colorblindness

@marcamos @chillicampari

@marcamos that is very cool. Thanks for sharing
