How to change the border colour of selected events

[Jon]

Currently when an event is selected in a scheduler a black border is applied. This is not very apparent and I'd like to change the colour and thickness to a red or lime green to make it stand out more.

Which css class do I need to override?

Thanks

Sorted... this was my override...

.k-event.k-state-selected {
    background-position: 0 0;
    -webkit-box-shadow: 0 0 0 4px #0f0;
    box-shadow: 0 0 0 4px #0f0;
}
