I am sorry for not sharing enough details. I tested both Chrome and Edge browser. Here is the steps to replicate the issue.
Navigate to dynalist.io to add as an app.
At the top right, click one three dots in chrome.
Click More Tools.
Click Create shortcut.
Enter a name for the shortcut and click Create.
Now the dynalist should launch in a separate tab like an app.
As shown in the screenshot in my post. The tab color at the top will be blue. It doesn’t matter wheather it is active or inactive. The tab color doesn’t adopt to the browser theme. So I was wondering if it is possible to edit that color?
I hope I explained clearly. Thank you for your response.
