Could you pleas send us the snap of that thing ?
Have a view on this…
Check the property explorer from UI Explore, it could there is a property indicate to check mark color
It is completely dependant on the Selector attribute like class, icon etc.
If you need more help, Kindly show us the selector in UiExplorer
I hope you have enabled the scripting in both SAP application and you are able to inspect on the elements in the SAP. If yes, you can use uiexplorer and indicate on 2 elements and see which attribute is changing with color.
Based on that, you can use get attribute and check the color.
