@julian , Thanks
I guess Panel is better for the colour scheme I have used.
Is it possible to customize the display of widgets only on certain pages?
There is an issue open to add areas, but for now, you have to add them yourself.

If you just want to change some css, you can use the class that is added to the body tag, and add to the custom css section ike so:
body.page-recent div[data-widget="theWidgetName"] {
color: orange;
}
