Colour should be chosen with an individual's personality in mind. High-energy people may need low-energy colours in the bedroom so they get a good night's sleep or vice versa.
Colour should be chosen for the appropriate emotion or job at hand wherever possible.
Children generally respond well to colour, especially primary colours that are clear and bright. Colour that stimulates the mind makes a child more reflective or inquisitive. Colour that encourages fun and play, whether educational or just good old-fashioned fun, makes your child feel content.
Colour will bring an emotional response for most people. It may bring happy or sad memories, positive or negative. Certain colours, fragrances and textures instantly take me back to my childhood. I recently worked with a client choosing the interior colours for their renovated home. One of the colours I had chosen would have worked very well for this particular situation. I was aware that my client was unsure of the hue but seemed to accept that it would work well. On the second visit she told me she had thought about the colour and, no, she wouldn't like it because it reminded her of the family's old farm sheds. They'd left the farm 13 years previously and that was where she wanted it to stay.
