James White has a fresh underlying green which creates soothing, calm, airy feeling rooms, so is particularly useful for darker spaces. James White was first created for a pretty garden room, so has a fresh underlying green. When used with no contrasts it creates the most calm and airy of rooms, with a particularly soothing feel so it is often favoured in the bedrooms of the super stressed. It will look more green both when used in contrast with All White and in north facing rooms. White & Light Tones Undercoat.
