An image conjures up a mood, an atmosphere and a useful palette of colour with which to develop your ideas
Here are three suggestions for how you might approach this phase
1. IMAGE LEAD
Your interior concept could begin with one or more images from which you could extract a range of colours.
2. CLEAN LINES
Likewise, most images will perform admirably when placed on white walls
adding the colour or interest to an otherwise plain space.
Alternatively if your decor is already established I can search an archive of imagery to enhance or embellish it.
