Can the colours of your bedroom affect your sleep?

Does your choice of bedroom colours affect your sleep? Yes I do realise your eyes will be closed, however the colours in your bedroom will affect your state of mind before going to sleep. Your bedroom should be a sanctuary, where you can leave all worries at the door and relax.
The colours need to be calming not stimulating. Now I'm not saying your room has to be bland and boring, think spa, think dreamy, think Zzzzzzzz.
Equally the colours will allow you to wake up to a calm area and your mood relaxed, after all your bedroom is the first thing you see in the morning and last thing you see at night.

My top tips are

• Use a colour wheel. The colours opposite each other compliment each other, however they are energising and vibrant when used together. The colours sitting next to each other are harmonising, for a bedroom pick a more muted colour and use the colours alongside it on the wheel for accessories/soft furnishings.
• Always try the colours/fabrics together as small samples before buying.
• Paint the ceiling a light neutral colour to open up the room.
• If your room is dark, enhance the light by using muted pastels, greys and off whites.
• If your room floods with light you can use a darker colour as an accent to the soft colours on the walls.
• Also use colours to warm or cool a room depending on the general temperature of your room.
• My palette choice would include airy, soft blues and greens with fresh off white linen bedding. A real sanctuary.
