browser.display.document_color_use

[Tiagoquix]

Hello.

I believe that in a similar manner to browser.display.use_system_colors the pref. browser.display.document_color_use is also related to color/contrast settings.

It controls this part in the settings (the radio button toggle):

I believe browser.display.use_system_colors is now behind this new Manage Colors... button.

On Linux, the contrast setting is OFF by default, but enabled on Windows (Automatic).

I guess we should set this to OFF (value 1) for all Arkenfox users too?

I took a look at Tor Browser settings and they don't seem to change this pref. there.

Thanks in advance for your attention.

There's a bigger issue with colors overall - in that not all colors are protected, and we must allow users to have some control for accessibility. RFP already protects as much as it can for now - what it needs at some point is for RFP to allow some presets e.,g HCM (high contrast mode) etc and lock everything down so users fall into only a few buckets

For now, should we force browser.display.document_color_use to 1 (OFF) in arkenfox?

I don't think so, but I've left this issue open to revisit - css colors is a bit messy and complex to say the least

Hi @Thorin-Oakenpants, what do you think about this for the next release? Thanks in advance.

nope - it's going to take time to assess it and right now I don't have time
