RE: High Contrast support with Browsers.

Fully agree, I just wanted to keep the two components of the UI separate. As they are different. One is web specific and the other is application specific. So how do we go and report these issues to the vendor? Never done it.

Sean, it is my opinion that not only the UI should change but that the colors chosen in high contrast mode should be passed through at the option of the user to the web page so the web page itself can be presented using that color scheme.  This could take several different paths such as the browser applying the user’s colors through a user style sheet or another approach.

I would like to drill down a bit and seperate the Web browser view port from the Browser UI.
1. The Web Browser View point I would assume is the responsibility of the web site.
2. While the UI of the browser (dialogs, alert messages, menus, ETC) that controls or you interacte with the browser is the vendor issue.

Based upon the responses to my original question and correct me if I am wrong. In a nut shell, the actual Browsers UI isn’t honouring the OS high contrast schemes.

I’d also say that the high contrast offered by Chrome is not sufficient for the needs of users with low vision.  It’s an SVG filter that is applied and is not always effective and doesn’t provide the flexibility that Windows high contrast mode offers.  It sometimes makes content have less contrast and a whole page filter can’t solve specific contrast situations on every part of a page.  Windows High contrast mode offers the ability for users to customize the color of certain types of widgets, text, and backgrounds with the colors that work best for them.

Apple’s macOS has an interesting increase contrast feature which seems to work with standard components and increases the contrast of essential lines and text to above 7:1 ratio.  But it does not go as far as Windows high contrast mode in its flexibility.

Noting that on certain operating systems (iOS, Android, macOS, others?), high contrast is a low-level setting that affects ALL output at the operating system level (what’s sent to the video card/monitor), while on others (Windows, others?), it’s a setting that software needs to be specifically coded to read and then support/implement.

All,

General query in relation to high contrast with browsers. Should the browser honor the OS high contrast settings or should the CSS override the OS high contrast? My view is the browser should honor the OS high contrast settings. Not sure if this is the case now.
