Keep the lounge away from the wall and it'll look bigger.

Hi all ! New to this forum so any help would be appreciated House is only around 10 years old but we are going to repaint Half the house is weatherboard , and half plaster (as per photos) We are wanting to go with greys , we are thinking darker grey weather board and lighter plaster ? The aluminium joinery is a light grey (almost exact to Dulux Timeless grey) We are struggling to get the right theme or idea on what we should do We were thinking Dulux Taihape for weather board , but unsure what to do with the plaster.. Ideas or opinions much appreciated ! (Sorry about quality of photos , I ran outside in the rain just to post this)

I'm wondering about painting my bedroom in Dulux Titirangi which is the darkest sample on the wall. maybe paint the lamps in the soft green on the left. my partner thinks it will make the room too dark, opinions please! the room does have big windows but only gets late afternoon sun.

help, what paint colors should I use in a low light kitchen (dark kitchen]
