Colours have an immense effect on our psyche and there are many scientific studies on this subject.
The effect of the Winter Blues largely stems from the lack of colour around us, which is why we should look up colour theory and make quick solutions at home by being inspired by it.
You can buy sheets, quilts or other bedding in colours such as blue, white and soft purple if you are trying to create a calm atmosphere. On the other hand, colours such as yellow, orange and red promote a feeling of energy, cheerfulness and positivity, so it's always a good idea to include furniture items in these colours too.
This trick applies to textiles as well as objects and accessories: the important thing is to bring colour into the rooms of the house!
That way you can regain some liveliness, even when finding it outside becomes difficult.
