Light colours

Perfect staging

In addition to the right light colour for the individual product groups in retail, the overall lighting concept also requires more precise consideration. In this respect, ledxon believes that the successful interaction of ceiling lighting, as well as lighting on products, shelving, and refrigerated cabinets, is hugely important – coordinated light colours and brightness create a product display that is both perfectly lit and inviting. Together, the individual components form a perfect synergy in the lighting concept.

Colour diversity meets pure authenticity

Various approaches from colour therapy show how much light colour influences our perception. For this reason, it plays a particularly important role in foodstuff lighting. Placed in the right light, fruit, vegetables, meat, fish, cheese and baked goods seem more delicious and flavourful. Their natural colour tones are emphasised, making the foodstuff appear fresh and appetising.

Presenting clothing, cosmetics and jewellery in white light that has particularly high colour rendering makes them seem even more luxurious and premium.

Cheese & pastry

Cheese & pastry

Oven-fresh pastries, bread with a crispy crust and cheese that seems like it’s fresh from the mountain pasture – an accentuated yellow element in the light encourages the impulse to buy here.

Fresh fish

Fresh fish

Blue-toned lighting on fish and seafood creates the sense that they have been freshly caught. In general, the whiter the fish, the cooler the light colour should be.

Fresh meat

Fresh meat

A slightly red-toned light emphasises the natural red shades in meat and fish, highlighting their freshness.

Good light in three factors

Colour location

The colour impression a light source gives is determined by its colour temperature in kelvin. The higher the kelvin figure the cooler – or whiter or bluer – the light seems. The colours are roughly separated into three ranges: from warm white, to neutral white, to daylight and cool white.

Colour quality

The Colour Rendering Index (CRI) provides information about the quality of a light source’s colour rendering. The sun and incandescent bulbs achieve the ideal value: Ra = 100. In general, A higher CRI make sense if the object to be illuminated needs presentation that looks as lifelike and realistic as possible, for example fabric displays in a shop. However, it may be advantageous to accentuate specific tones on foodstuffs, for instance reinforcing the red tones in meat; in this case a lower quality of colour rendering may be preferred.

Colour consistency

LEDs vary in their colour and luminosity, and –to guarantee a constant light quality – they are divided into “bins” (sorting). The deviations perceptible by the human eye are determined using MacAdam ellipses. The usual tolerance range within a bin is at 3 MacAdam ellipses, 3 SDCM.
