No pure white: add a touch of yellow to the walls

A space demonstrating white color choices. The walls are painted a warm white with a small amount of yellow and a very small amount of red, appearing soft and not grayish under diffuse light on a cloudy day, and warm and not harsh under afternoon sunlight. The ceiling is half a shade lighter than the walls, also with a warm tone. One corner of the image shows a comparison with pure white walls; under the same lighting, they appear stark white, bluish, and out of place with the warm tones of the wooden floor, and they make shadows appear grayish-blue. The difference between the two is most obvious in the shadows—the warm white's shadows are warm grayish-brown, while the pure white's shadows are cool bluish-gray. The paint finish is completely matte.
Avoid: making the two look identical, using high-gloss finishes, adding other colors to interfere with the comparison, changing lighting conditions.

一個示範白色選擇的空間。牆面漆成一種加了少量黃與極少量紅的暖白,在陰天的漫射光下顯得柔和而不發灰,在午後的陽光下顯得溫潤而不刺眼。天花是比牆再淺半階的白,同樣帶暖。畫面的一角以純白的牆面作為對照,同樣的光線下顯得慘白、偏藍、與木地板的暖色格格不入,並且把陰影襯托成灰藍色。兩者的差異在陰影處最明顯——暖白的陰影是溫暖的灰褐,純白的陰影是冷的藍灰。塗料的光澤是完全的霧面。避免:讓兩者看起來相同、使用高光的漆面、加入其他顏色干擾比較、改變照明條件。
