Description from store *** Grayscale Black & White Colors - High Contrast Theme & Skin Remove all colors from web pages, convert them to black and white colour. All high contrast themes & skins are included. Change or invert the color scheme to make webpages easier to read. Turn on/off negative effect (high contrast) for all webpages on the same domain at once! Change the color theme of any webpage in one click. Color setting is saved and loaded automatically on every domain. "Grayscale Black & White - High Contrast Theme" lets you browse the web with your choice of several high-contrast color filters designed to make it easier to read text. When you install this extension, all pages are "inverted", so black becomes white and white becomes black. Press the "browser action" icon in the toolbar to toggle it on and off, or customize your settings on a per-site basis. Use a convenient keyboard shortcut to quickly change your settings while you browse. Other extensions try to change the default colors, but this ends up breaking many popular websites. Only this extension applies filters to your page that invert almost everything - the only exception is photos, which are left alone. Also note that the Chrome web store and other built-in pages like the New Tab page and Settings pages are unaffected - extensions like this one are not allowed to modify them, by design. *** How to "Grayscale Black & White - High Contrast Theme" : 1. Go to any webpage and click the "Grayscale Black & White - High Contrast Theme" toolbar icon. You can choose these themes & skins settings: - Grayscale - Inverted Grayscale - Inverted Color - Increased Contrast - Yellow on Black 2. Click "Set as default scheme" to Save the settings, or Disable it completely to restore the default colors of websites. Restart browser or refresh all tabs for the new setting to take effect. 3. Rank the extension with 5 stars and tell your friends about it :)

  • (2020-01-09) 7267 MMBD: 画像の確認をするために必要に応じて使用しています。シンプルで使いやすいです。
  • (2019-12-19) Pablo G: I can't read webpages with night themes more than 10 seconds (headhache, ghost letters...), this plugin help me a lot.
  • (2019-05-24) Toto Ressorp: Made pages too dark, without any way to adjust them, but even then I would've been okay with it. But it also slows down everything and breaks gmail so it had to go
  • (2019-04-10) Tim Causey: Does not work.
  • (2019-03-27) Harun Doğdu: kullanışlı bir uzantı
  • (2018-10-01) Dylan Stricker: I converts pages to grey scale but it also increases the contrast and makes all pages come to a crawl. Too heavy for it to be useful for me.
  • (2018-09-27) Tristram S: Great idea, implementation is shoddy. I got this extension to make facebook grayscale to make it less engaging {harder to get sucked in} but not technically less useful {can still check messages and look up events}. Unfortunately, it keeps kicking on and off. Gray for a minute, then it flips back to color. Also, the grayscale option doesn't look like the screen cap above. It makes a lot of stuff just black, so I can't even see the notification / message icons to click on them. I'm on a high quality, calibrated display, so I don't think it's an issue on my end. If this worked I'd kick in a few bucks in gratitude. For now they get a reserved thumbs up. Nothing awful, no negative effects.... just doesn't really work.
  • (2018-08-13) L S: It works inconsistently and slows down web pages. I don't know why this isn't a basic accessibility feature in google chrome to begin with...
  • (2018-07-26) KYNGSTON PLAYER: muito bom adorei esse ja usei ele bastante tempo ele é top
  • (2018-07-25) Rob McGuire: Pretty much exactly what I was looking for: Something that makes all websites monochrome to reduce attention drain. It's not perfect, though: It doesn't work on all websites (e.g., the chrome web store), it causes vertical screen tearing/freezing sometimes (e.g., on Google Inbox).
  • (2018-07-17) stevieforest69: Werkt niet voor Outlook Mail!
  • (2018-07-15) J. Scott Elder: Sacrifices resolution for contrast. Sure, one can print grayscale, for example, but then the text is not legible on a printout. So what's the point? Got this for Google Maps printout on black and white printer. Immediately deleted it thereafter.
  • (2018-06-24) W M: Very good. Touches less the views to read.
  • (2018-06-18) Harvey Lang: it doesn't work...pages are not in a higher contrast...nothing happens
  • (2018-06-11) amit nigam: doesn't work. waste of time
  • (2018-05-21) Антон Соломатин: При включении этого приложения - пропадает возможность скроллить колесом мыши некоторые сайты.
  • (2018-05-17) Diane Watters: I think it works Great, although I am not going to keep it, was seeking the black theme and where posts, pictures remain in color, My eyes though, Thank you for developing this !
  • (2018-05-10) BC Kadwa Sach: loved it
  • (2018-05-09) "This actually works!" -- is the best rating of all. hard to read pages - because of site designer's penchant to be oh so clever - are now readable. And, the contrast alterations are sticky to specific site - not just page. Tahnks for that.
  • (2018-05-07) richard hunt: Not working so well in Windows 10. Increased Contrast seldom works, gray scale seems to dominate and not respond to off.
  • (2018-04-19) Matt Zerfas: This extension causes severe functionality issues with a number of sites (e.g. yahoomail and amazon video). It's a deal breaker when there are other extensions that don't have this issue. Last gripe is that videos in fullscreen mode do not convert to grayscale.
  • (2018-04-06) Cesar Silva: Though I liked the interface, I faced some incompatibility with gmail tab. Thanks
  • (2018-04-04) Rich Blaikie: Loaded Trojan Horse - avoid
  • (2018-03-16) Tony Maeller: This was once a very useful app, and for many web sites it still works well, but now it seems to bog down or completely disable Google App pages. And now (probably due to Chrome updates since I started using this) it also requires refreshing the assigned tab to apply the changes. And, we wouldn't even need this plugin if web designers weren't forced into the disabling fad of presenting their site info with super-low contrast. Time to look for another app to help fix this.

    Your "Increased Contrast" setting is just *great* for my 73-year-old eyes. However, I also use the app "Toggle Distilled Page Contents" a lot, and for the text displayed in it "Increased Contrast" fails, and my tired old eyes must once again strain to see gray-on-white text. Would it be possible for you to look into becoming compatible with "Toggle Distilled Page Contents"? My failing eyesight would be mo$t grateful to see this implemented.
  • (2019-06-24, v:2016.9.9.2) prashant kharade: Not applicable to all web pages
    This extension is not applicable to all web pages. We need to reload web pages in order to apply. Is there any way to apply this extension to all web pages without refresh.
  • (2018-05-09, v:2016.9.9.2) It breaks GMAIL
    Hi I originally loved it. Now i discover that your extension is interfering with Gmail - causing freezing for 20 to 30 seconds at a time. This problem will make the ext useless. NOTE - the extension does NOT now allow page-specific setting for enable/disable. Fixing that bug MIGHT solve the problem. Otherwise, this bug will kill you. So sorry, TomH
  • (2018-04-07, v:2016.9.9.2) Jason Piatt: Does nothing
    Windows 10...the extension did nothing. Installed it, enabled it, nothing. Tried all the different settings (grayscale, high contrast, yellow on black, etc.), nothing. Tried several different pages and restarted Chrome. Nothing.
  • (2018-03-20, v:2016.9.9.2) Janusz: Problem with gmail
    The extension is great but unfortunately I had to get rid of it since it interferes with gmail.
  • (2018-01-29, v:2016.9.9.2) Karl Anton: Failure
    Doesn't work! A Previous installation worked but it went nuts! It came on unanounced and I couldn't turn it off. Im trying it again this time I hope it works propely. KA
  • (2017-12-31, v:2016.9.9.2) Jim Considine: Interferes with use of Ebay
    I really like how Greyscale contrast helps me see things better on Chrome, however, being ableto use Ebay has some importance to me as well. Unfortunately, when I'm on Ebay and have Greyscale activated, although it makes things easier for me to see, it also prevents me from being able to bid on anything. I can't type numbers or anything in the auction bidding areas (bid input boxes). It sure would be great if you could fix that problem.
  • (2017-11-30, v:2016.9.9.2) Paolo Sioli: does not work with gmail
    hi congratulations for your extension, really useful but it does not work good with gmail when installed and active, with no settings it's possible to send a new email in the new email box, it's impossible to select a recipient. when disabled, it works please help!!!

  • (2017-10-14, v:2016.9.9.2) Hannes Grebin: Grayscale is high contrast GS
