  • (2019-08-20) Ruanne Bornman: Works Great, thanks
  • (2019-08-12) Stuw R: I DON'T THINK IT'S CORRECT I'm red-weak colourblind. A simulation of such colourblindness should make red darker, and this doesn't. In fact it makes it lighter. I've checked it by looking at SMPTE colour bars and a colour picker, and I think it's adjusting for my colour vision (as far as is possible) rather than simulating it for normal visioned people. I think the green options may be OK.
  • (2019-08-05) Remzi Cavdar: This extension is not supported anymore. This project is fully abandoned by the developer, see GitHub: https://github.com/LeonardoCardoso/Colorblinding I would like to warn everyone, this extension has some bugs and all have been fixed on GitHub only the developer doesn't want to push an update. My advice would be to use something else.
  • (2019-07-01) Sugar the Cat: It's good
  • (2019-05-24) Jim T: Working in 2019, on a Mac in Chrome - I don't see any issues others mention with runaway processor usage or shifting of objects (I suspect it was more likely triggering earlier verisons of Chrome that were known for their high cpu usage). I'm quite happy with its ability to demonstrate colorblind issues - full thumbs up!
  • (2019-05-21) Iris Shields: Doesn't work. Uncaught ReferenceError: execute is not defined
  • (2019-04-26) Prashanth Sandela: Thanks for your effort on this. Helps a lot while designing websites.
  • (2019-04-22) James Aarya: Best tool, Thanks you so much!!!
  • (2019-03-20) Justas Stromilas: Does not work
  • (2019-02-14) Daniel Bonifacio: Amazing. Nice work!
  • (2018-11-21) Cotton The Cat: No está mal, la calidad al ver videos disminuye un poco, pero está bien.
  • (2018-10-26) Kitty Hurley: I depend on this nifty tool daily to ensure my interactive mapping applications meet all audiences color spectrum's. Highly recommended!
  • (2018-05-03) Iván Quiñones Werth: los cambios no son apreciables
  • (2018-02-04) Matheus: Muito bom...recomendo a todos...
  • (2018-01-20) Jaroslaw Szymczak: The CPU usage goes through the roof even when functionality is disabled. What does it do really apart from what's written? Or is it just bad code?
  • (2018-01-18) Mark Sandland: Simulates colorblindness effectively, but also causes elements to move around on some pages.
  • (2018-01-03) Corey Turner: I like it, but I'd prefer to have the options sorted by most common color blindness.
  • (2017-11-06) Max Aitkenhead: Works great on most websites but doesn't seem to work on local html files, no good for developing unless its all ready hosted.
  • (2017-09-15) John Laur: Although this extension does appear to simulate color vision problems, I wanted to give a caution to others. As noted by other reviewers, Colorblinding has high CPU use, the amount of memory it uses is very high (several hundred MB) and fluctuates rapidly, and it communicates over the network a good deal. This occurs even when the simulation is disabled. I cannot fathom any reason why it should do any of these things, and I am suspicious of it. The project is open source, so I am hoping to conduct some further research on why it does these things, particularly why it makes outgoing network connections.
  • (2015-10-21) Clarence Wee: Does what it says on the label. However, the CPU usage went straight up even if I did not set colorblind mode on any of my tabs. On a Mac, Chrome 46.0.2490.71.
  • (2015-05-15) James Tweddle: very interesting! thanks for making x
