A lighter colour trim is always a good option. If you want to save some money and time jump onto https://www.monstashop.com/ They can send you a free colour deck with all the whites available. Or you can get your Dulux colour matched! All without leaving the house!!

To Modernise this without rendering or retiling the roof I would probably recommend to go darker with the trims. My top pick as a colour consultant would be Dulux's Domino for the trim. It will be a little bolder and create a more modern contemporary feel. You can see it pictured below as the trim. Obviously this house has painted their bricks in the shade "teahouse" however it will still look much better on your 1980s "peru" colour bricks! Don't hesitate to contact me if you need any more help colour wise!

If the trims and doors are already painted then go for it for a neautral background look that has no character. However if they are stained timber then never paint it white and work with what you have. Best of luck Dr Retro of Dr Retro House Calls

Try dulux snowy mountains. Just hope you plan to bring some colour and textured elements into space. With the tiled light floor, the effect might a bit cold.
