Color of light

It is often considered a suitable shade of lighting, is a warm or cold shade a better option?

Kelvin (K) tells you what color white light is. The higher the Kelvin value, the colder the light will be.

  • 1700K-3500K Warm white (stuffy/yellow white)

  • 4000K-4500K Natural white (pure white)

  • 5000K-6000K Daylight (Bluish White)

The choice of colour temperature is influenced by the need to use the space, in areas requiring precise work, lighting should be bright and cold, while in residential buildings the main focus is on one's own preference. In addition, the size of the space and sufficient colour resilience (CRI) should be taken into account.

The colour temperature of an ordinary filament lamp is usually about 2500K, which is warm white. Today, we want a cleaner white light color of about 4000K.

More than 4000K is recommended in office space, and the advantage of daylight lighting (over 5000K) is an uplifting effect. Restaurants often use warm tones to create atmosphere.

Choosing the color of light

• Whiter hue increases efficiency in offices

• In conditions requiring special accuracy, a colour temperature that repeats daylight is required

• The colour of the light affects the appearance of the interior and objects

• Attention adequate colour repetition (CRI)

• Outdoor lighting also includes attention to the shade of the façade

The color of light affects man

Light has a major impact on human hormone production. Smart lighting can be used to adjust the tone of lighting to support the circadian rhythm. In the morning, cool lighting stops melatonin seration, which helps to wake up and make working more efficient. In the evening, warm-toned lighting helps to relax and increase the production of melatonin. Light also increases the production of serotonin, which has an impact on mood, learning and well-being.

When considering the color tone of the lighting, remember these: 
The warmer colour of the light relaxes and increases the atmosphere and comfort. The white tint adds precision to the work, brings a fresh vibe and reproduces the colors more cleanly.
