Advice needed: what evergreen/colour all year round shrubs?

Hi

I have a patio area of my garden and a walled garden  patch where I want to plant evergreen shrubs and all year round colourful plants, shrubs, bushes etc.  

i want to plant some in pots (mostly sun/light spot) and then the walled garden patch is mostly in the shade.

I would love some recommendations of what I can plant now in September that will look green and tidy all winter long and year round?

thank you
