Color temperature 2700K: makes brown lean red, not gray

A dark space with a unified color temperature of 2700K. This color temperature makes dark brown wood appear reddish-warm, bringing out the color bands of walnut and suppressing the grayish-purple of smoked oak; if raised above 4000K, the same wood would turn into a dull grayish-brown, making the entire space look unlit. All light sources in the entire room are of the same color temperature, including linear lights hidden in wood joints. Avoid: using neutral white and cool white light above 4000K, mixing different color temperatures in the same space, using light sources with low color rendering index, allowing too large a difference between natural light and artificial light color temperatures.

一個色溫統一在二千七百K的深色空間。這個色溫讓深褐的木偏向紅暖,胡桃的色帶被拉出來,燻橡的灰紫被壓下去;如果升到四千K以上,同樣的木會變成一種沉悶的灰褐,整個空間看起來像沒開燈。全室所有的光源都是同一個色溫,包括藏在木縫裡的線性燈。避免:使用四千K以上的中性白與冷白光、在同一個空間混用不同色溫、使用低演色性的光源、讓自然光與人工光的色溫差距過大。
