No colour could be more autumnal than mustard. A warm yellow hue that has been trending in fashion and homeware for the last few months and is set to stay on the hot list into Spring 2018.
I have done a Pinterest board with some gorgeous pictures from other users to get you inspired for the trend.
How to make it work
I would recommend using mustard as an accent colour. It works beautifully with neutrals including navy, grey and white. If you want a bolder look you could even use a small amount in a monochrome room too.
