Color rendering (Ra value)
Color rendering relates to how naturally the colors of objects appear under certain lighting conditions. In the bathroom, this is particularly important when looking in the mirror in order to show natural skin and hair tones and the color of clothing or make-up.
This is represented by the Ra value, also known as the CRI (Color Rendering Index). On a scale of 0 to 100, it specifies how accurately a light source renders the colors of objects in comparison with natural daylight. The higher the value, the closer the rendered colors are to the original. A Ra value of 100 corresponds to color rendering as achieved by natural daylight. At lower Ra values, colors look distorted or altered. Overall, a high color rendering helps to create a natural, pleasant atmosphere in rooms.
Our tip: Values of 80 Ra and above are a good reference point for interiors. In the bathroom, a value above 90 Ra is recommended for the natural rendering of skin tones.
