London - Remember the mantra “blue and green should never be seen”? Well, now you can shelve that design rule for good. In fact, vivid blues and turquoise look fabulous against a clash of emerald green.

Peacock shades are a must-have and will instantly infuse any room with a shot of jewel-like glamour and colour-blocking cool.

“Living rooms, dining rooms and bedrooms can be transformed with blue and green shades and bright colours indoors will lift the room as well as your mood,” says Rob Jackson, senior buyer at online luxury lifestyle store, Achica.

“If painting a whole room is too much, a statement wall, cushions, throws, photo frames and vases filled with peacock feathers complement neutral base colours.” -
