Paint suggestions for dark room

[lustforlife]

We are wanting to repaint our very dark living room which is in the middle of our conservatory and porch (so doesn't have any windows!) it's currently a warm grey which I really like but just makes the room so much darker.

Looking for recommendations for a light, neutral paint colour please? I've seen the dulux light and space but the reviews are very mixed...

I've got light and space in my office. If it makes a difference, it's not by much. I also have it in an alcove in my living room. It's non washable if that matters to you. I wouldn't use it again.

I did a lot of research on this as we have a dark hall, stairs and landing. The choices are to embrace the darkness and make it cosy - improve the lighting too to make it workable. Or to go for a slightly "dirty" shade of a light, bright colour. If you use a very light, pale colour it just looks dull as there's no natural light reflecting off it.
