Description from store
Color vision is unfortunately not granted to everyone. Approximately 10% are affected by a reduction in their ability to perceive colors. Let's get color blind tries to raise awareness by letting you simulate colorblindness. Such that you can easily experience the information a color blind person receives. Such that you can learn about colorblindness, check your web pages for accessibility or explain your condition to others. It is even possible to change the severity of the simulated condition.
Additionally a daltonization filter can be used to improve the information received by those who are subjected to colorblindness. Results may vary depending on the severeness of each individuals personal condition.
The color deviciency simulation is based on
Gustavo M. Machado, Manuel M. Oliveira, and Leandro A. F. Fernandes "A Physiologically-based Model for Simulation of Color Vision Deficiency". IEEE Transactions on Visualization and Computer Graphics. Volume 15 (2009), Number 6, November/December 2009. pp. 1291-1298.

- (2022-03-16) Jon Harrison: Once installed you need to refresh the page. Set the settings you want, save them and then refresh the page. It does work!
- (2022-01-12) пепная лапка: very very very cool
- (2021-11-06) Jack Cunningham: It doesn't work at all and I saw other people review and dose not work for me, dose it not work on windows?
- (2021-09-08) Christopher Graham: Works once you figure out how to enable it. Should prompt you to refresh the page after enabling it and saving your initial settings. Obviously I'm taking a huge leap of faith it's accurately representing colorblindness.
- (2021-06-02) Leviticus: It does work.
- (2021-02-18) Path Lab Education: Simple, effective, does what it says. You do need to refresh any tabs that were open before you install. That might be where some users have issues.
- (2021-01-13) Pablo Frias: Doesn't work and options exist that do.
- (2020-10-07) Floris_Fireball (Floris_Fireball): I solved my problem. You may need to reload your website after turning this on. Some problems I had was slow response times, and often having to double or tripple click the buttons before they responded. It does work now though :D Thanks
- (2019-03-30) Lily Anatia: doesn't work at all.
- (2019-03-13) Doesn't work
- (2019-02-19) Karoliina Järvinen: It's lightweight and does a good job of simulating the most common types of colour blindness. The tritanopia simulator is not 100% correct. "Yellows" should appear whiter and saturated blues should appear more teal. Tritans shouldn't see yellow or blue at all. This number should be invisible -> https://i.imgur.com/OUJWOZb.png
- (2018-09-19) Eliot Budde: Works quite well! Definitely helps me as an a11y focused dev. >The only reason it potentially does not work for some users is because the site they are on have poor contrast ratios.
- (2018-07-05) I can't get it to work... Can someone help me?
- (2018-03-09) Marten Tacoma: Both helpfull in seeing more contrast where I normaly don't see it, and in helping others to understand more of what I see
- (2018-02-28) Job van der Zwan: It works! Even with CSS it seems? And I can tweak the strength! This is already making reading some plots on Wikipedia much easier, thank you so much for this!
