Visible difference of formatting in Darkmode

[Bozo0511]

Title: This would be an upgrade on an existing feature, text formatting in the dark mode.

1. What is your original issue/pain point you want to solve?
   By using copy and paste, I am not aware that the text color or formatting has changed.
   And I send almost invisible text to my customer.

2. Which are one or two concrete situations where this problem hurts the most?

I copy a text from Mattermost dark mode into my note.

So far this looks fine, and there is no warning that the font color or formatting is changed.

When you switch to the light mode, the note is barely visible.

3. Why is it not solvable with the Zammad standard?
   There is a way to resolve this pasting without formatting: Ctrl + shift + v.
   People tend to forget to use it and don’t see any visible change in the formatting. And update the ticket, not being aware of any changes.

4. What is your expectation/what do you want to achieve?

I would expect a warning that indicates that the formatting is different in light mode.

Or

If you use copy/paste paste without formating, and add a short cut ro paste with formating.

If there is any more useful information, feel free to share it all (e.g.: mockup screenshots, if something is UI related, or the API URL/documentation URL for a service you need a connection to).

Thank you and have fun.

I would like to add additional details based on my experience, which is very similar to the issue described above.
In my case, I am copying text from Trend Micro Vision One, which I also use in Dark Mode. The copied text preserves its styling (including color) and when pasted into Zammad, the text remains white.
This is not visible in Dark Mode, so everything appears fine. However, the moment the interface switches to Light Mode (or when the recipient views the email), the text becomes completely invisible on the white background.
From a user perspective, this does not feel like an intentional or helpful feature.
Having white text on a white background without any warning makes it very easy to send unreadable content to customers.
I would expect Zammad to detect such cases (e.g., text color matching background color) and either automatically adjust the text color or provide a visible warning to the user

I am attaching screenshots that demonstrate that after pasting, the text remains white and is therefore not visible on a white background.

In the end, this is a very difficult topic, also about expectations when people think the formatting and color should stay, and when not.

Normally, you should always use “paste without formatting” in such situations.

I agree this is a nuanced topic there are valid cases to keep formatting and others where it hurts readability. In practice, agents often forget to use paste without formatting, which is how invisible text slips through. A lightweight safeguard would help: for example a small warning when pasted text has low contrast in the current or opposite theme, or a brief pre‑send check that says “Some text may be invisible fix or send anyway.” An optional “normalize colors” action or making paste‑without‑formatting the default (with an explicit “paste with formatting” option) would also reduce incidents. We’ve had customer complaints where content was effectively invisible i.e. information loss so a simple warning or check would likely prevent most cases.
