Colour wheel

Digital group today and we were talking about the colour wheel  etc  First in general terms, using the above and then we listened to a discussion between Blake Rudis and Bob Wild.

I've heard Blake Rudis before and he is very much worth watching.

Overcast and cold!!  No rain .....Yet????     Beautiful sunset!
