I've spent ages looking at how I could do this, and how many colours to include. We don't have a huge temperature range in this country do we?
I think I've managed to get 11 different colours...pushing it to 14 colours if we have extreme weather this year.
I've gone in steps of 4 degrees temp between colour change. 5 degrees didn't quite give enough...I'm also looking at including both the day and night temps.
