Grey works in most homes, this is a palette with several warm grey colours.
You can order this palette to test which tones of grey you prefer.
Some go towards the trendy colour Greige and some towards warm green.
If you have a north-facing room, the colour will usually be slightly cooler, while a south-facing room will have a warmer effect. Therefore this palette is perfect if you are wanting to test what fits best for your specific conditions.
