Hi Joe,
Just to let you know, on some custom includelets which I've recently added to a page, the panel colour I chose is not showing when I publish the page.
Kind regards
Kathryn
Thanks for reporting this - I'd also just noticed this myself and have fixed it.
The Panel Colour picker should have been showing a preset list (Primary/Info/Warning etc) but was accidentally showing the colour picker wheel.
If you go back to the includelet options you can now correctly select the colour.
Thanks
Joe
