I suggest the following to add the color option:
line 43: "color" => {"short" => "c", "check" => qr/^\#[a-fA-F\d]{6}$/},
line 435: <code><b>color</b> </code> - short: <code>c </code> - type: hexadecimal - Hexadecimal Colorcode, Example: #FF0000 (only Android >5.0, Windows 10 & Client APP)<br>
Hi, and welcome to the community.
Your post is rather hard to find. My suggestion: Look at the top of the module code for the maintainer of the code. And then send him your modification request by personal message here in the forum.
