Change header separator color to Outlook default

[cnmicha]

Hi,

how do you think about changing the default value of the preference extensions.replywithheader.header.separator.line.color to #1E1E1E which is the header separator line color of Outlook?

What was the idea behind choosing the current default color (#B5C4DF)?

If you like, I can provide a pull request for this.

Thanks!

@cnmicha When initially developed the RWH add-on that time I took a color code from Outlook. I think the Outlook client still uses that color. I can see with my macOS Outlook client v16.52 (21080801).

May I know where do you see a black color? web version?

Looks like Outlook has different default styles in Windows vs Mac. While css is used in email sent by O365 Outlook, I simplified styling into html tags without css and ended up with below html snippet. I had 24 hour clock but otherwise regular US English settings. Note how separator line is produced by O365 Outlook client in Windows, with line color E1E1E1. Below snippet is 100% similar than how replying or forwarding with O365 Outlook client in Windows.

<div><div style="border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0cm 0cm 0cm">
<p style="margin-top:0;font-family:Calibri,sans-serif;font-size:11pt;">

</div></div>

@anttiisoaho Thanks for providing the HTML string; it is helpful for understanding.

@cnmicha @anttiisoaho I will change the header line default color to #1E1E1E on v3.0.0 onwards; until then, please use the RWH add-on options to change the color.

@jeevatkm just note the corrrect color value: #E1E1E1 - I believe there was originally typo by @cnmicha. Additional notes:

• HTML snippet above is exactly what O365 Outlook client in Windows use for separator+headers, with note that I simplified headers text style from css into <p> tag
• From/To/Cc email addresses are inside < > and not inside [ ]

@anttiisoaho Thanks. I will take care of it.

@cnmicha @anttiisoaho I'm working on the WebExtension version of RWH. The branch is here.

I require a sample string of the following in multiple languages for a Plain Text email.

Plain text example from O365 (US English) if this is what you wanted - there is no difference in reply or forward so this applies to both:

-empty line, cursor blinks here when starting to reply or forward-
-empty line-
