Whit + colour + gold. Never fails: gold 'lifts' an otherwise cool or bland combination and allows cooler colours to be used. the cooler colours stop the gold from being too 'brassy'
Pale grey in the en-suite, pale tiles on the floor..good mix. Creates light. Use more than 1 gold mirror to brighten
Comment about light greys: can appear luminous in well-lit spaces
Open cupboards - don't affix doors
Double mirrors with shelving
Have space to do this in the ensuite
