Add this line to grey.xml which is located in skin.transparency > colors
in Includes.xml, change all instances of darkblue to red
For RecentlyAdded, open the Includes_Home.xml
Depending on your svn and whether you have made other changes, the line numbers from 3.11.5 may not be accurate for you but look for blue and lightblue in the focusedlayout sections of:
at line 1297, change blue to red
at line 1325, change lightblue to red
at line 1518, change blue to red
at line 1546, change lightblue to red
Obviously, you will have to make these changes every time Includes_Home.xml is updated.
The weather icon is not mine, ronie added checkboxes in Settings > Skin Settings > Icons:
