Any advice or website suggestions to help choose paint colours, accent wall colours etc ?

[OhMyGiddyAunt]

Our living room is not a regular shape - quite long and narrow and part of it is double height. At the moment the walls are all a very neutral mushroom colour and in need of redecorating.

I want to change it and fancy a sort of RAF blue/grey colour (inspired by a decorative soft furnishings item I want to use in the room that has that colour in it).

I want some idea of what a whole room would look like painted in that colour and also what if only certain accent walls painted in that colour . If only accent walls were that colour how would I find a colour for the other walls? How do you know which walls should be the "accent" colour (especially if you have a non-regular shaped room)

Are there any good websites out there I could use for guidance or interior design decor advice? At the moment I don't know where to start

The dulux visualiser app can be helpful.

I find F&B website useful for complementary colours, they suggest colour schemes and matching whites etc. you can just find a similar F&B colour to give you an idea.

Thank you @TheOneWithUnagi I'll give the app a go tomorrow as I'm really confused as to which walls to paint/not paint and whether it will be too much.

Second having a look at paint websites, Mylands & Little Greene are also good Woodchip&Magnolia although primarily wallpaper also do paint & they show different combinations oh also House of Hackney might be worth a look.
