Live odds - colors - what do they mean?

[Daveo]

Can anyone please tell me what it means when you're looking at the live odds on SBR:

and some of the odds are sometimes shown with a red, orange or yellow background? What do the colors mean?

Much appreciated to anyone who can advise!

The red background indicates that the odds just changed. It turns orange after a few seconds, then yellow, then back to white.
