Can't tell which 'Filter message by:' button has been selected when in High Contrast mode
I use Windows 'High Contrast Black' because of my low vision, and I have no choice over this. When using the quick filter tool, there are buttons following the heading 'Filter Messages by:', such as 'Sender', 'Recipient', 'Subject' and 'Body'. I'm pretty sure that when using standard Windows colours, these highlight when in use, so you know which combination are affected by the text in the Quick Filter field. Unfortunately, when using High Contrast Black, there is no such indication. Clicking on the buttons does do the necessary filtering, but there's no indication as to when one or more of them have been selected.
I did find a Theme, 'Dark' that brought about the highlighting, which I was using just fine until the recent update, when the background colour to the message pane suddenly changed to White, which is of no use to me, as the brightness of an overall white page means I can't read what's on it. I went into the Options/Formatting, and selected 'Only with High Contrast themes' for 'Override colours specified...'. I thought this had resolved that issue, until I noticed I could no longer clearly read the marked as 'read' headers in the email list. This was because there isn't enough contrast between the text on these headers and the background colour as a result of the 'Dark' colour scheme. I therefore disabled the Thunderbird 'Dark' theme in favour of the 'Default' theme.
By disabling the 'Dark' theme, I could once again read the message headers in the Email list, but now I can't determine which of the aforementioned Quick filters have been applied, because the 'Sender', 'Recipient', 'Subject', and 'Body' have no highlighting when they are in use under the 'Windows High Contrast Black' theme.
Is there any way of making some kind of change so that I can tell which of those buttons has been activated? s

Sounds like this is a reportable issue. Please file a bug report at https://bugzilla.mozilla.org/enter_bug.cgi?product=Thunderbird&component=Theme
I've switched on 'High Contrast Black' on computer (Windows 10) I've set up to use 'Dark theme'
re : I went into the Options/Formatting, and selected 'Only with High Contrast themes' for 'Override colours specified...'.
In that section, Options/Formatting, click on 'Colours'. 'Background' can be changed to use 'Black' instead of 'White'. Do you have 'Black' selected ?
Re: Filter messages by: Sender, Recipients, Subject, Body
When not selected I see White text on Black background.
When selected, I see white text on mid grey background.
First of all, when I clicked onto the Bug reporting link, it asked me to log in. My username on Mozilla is Logan9Fingers, with the attached email being the Hotmail address that I use everywhere. It asks me for an email address to log in to the Bug reporting link, and it wouldn't accept it...the password was correct for the Logan9Fingers login that I normally use for Mozilla. Perhaps you can explain what I'm doing wrong.
Okay, now I'd like to thank both of you for replying, and in your case Mr Toad, for going to the trouble of trying to recreate my scenario. In answer to your questions, yes, I do have 'Black' as the background colour, and yes, the 'Dark' theme does allow the mid grey highlighting. My problem is that I can't use the 'Dark' theme because it overrides the black background of my message list and turns it to something that is a kind of off black (sorry, my vision isn't good enough to tell what colour it is). Because this is not a pure black, the message header text, such as the columns of senders, the columns of subjects, and the columns of dates, isn't the stark white on black that I need to read it. So I either need a solution to that background colour of the 'Dark' theme, or I need a different theme that has a pure black background, but that also highlights in some way, the quick filter buttons.
bugzilla does not use the same login account as the support system in which you are now posting.
Thank you for the heads up on the Bugzilla.
I wonder if Toad-Hall has had a chance to read the second half of my last message? I recall in the old days of Firefox, how so many issues could be resolved by the user going into this source file or that, and making changes to values that could alter things related to layout...so I was wondering if such changes were still possible? For example, making a colour change to the background of the 'Dark' scheme, or making a change to the highlighting around the quick filter buttons? Could these be tweakable by the user?
Did you try: Addons > Themes Choose 'Default' 'A theme with the operating system colour scheme' to see if it helps ?
As I mentioned, because the 'Dark' theme has a background that is slightly lighter than pure black, which means the 'read' message headers weren't contrasted enough for me to be able to read the text in those headers, I had to enable the 'Default' theme, because reading those headers was more important than seeing the highlighting around the filter buttons. However, the 'Default' theme under the Windows system colour scheme, 'High Contrast Black', hides the highlighting around the active filter buttons, and I still need those too.
Can the 'Dark' theme be tinkered with? Is there not a value that represents the background colour on the message list, that could be changed to pure black? If these themes can be created by users, they must surely be tweakable? I'm somewhat surprised that if you have specified the override of system colours in the Options/formatting/Colours screen, that a theme can then override that option.
