#TheDress or how differences in lighting affect people's perception of colour
Choosing the right lighting for a retail shop is fundamental. Whether it's accent, ambient or general lighting, the lamps and luminaires you choose can change the way customers perceive the colour of a room, the shade of an item in a shop window, on shelves and in displays.
In the worst case scenario, for example, the colours of a striped dress could be perceived as white with gold instead of blue with black...
You don't believe it? Just such a phenomenon triggered an internet hype in 2015, which caused a furore with the hashtag #TheDress.
Wiedergabe von Weißtönen ohne ultraviolette Strahlung
In verschiedenen Beiträgen hier im danholt Licht-BLOG habe ich die Bedeutung der verschiedenen TM-30-Kennzahlen erläutert und erklärt und wie Lichtdesigner und Anwender sich von ihnen leiten lassen können.
Der TM-30 ist jedoch auch für andere Akteure in der Beleuchtungswelt nützlich, einschließlich der Hersteller selbst. Bei der Entwicklung einer Lichtquelle geht es oft um Kompromisse - zum Beispiel können wir entscheiden, ob wir die Lumen (Lumen/Watt) oder die Farbwiedergabe in den Vordergrund stellen.
Colour enhancement based on TM30
When should we use such colour-enhancing light sources? This is an interesting question to which there is no simple answer.
First of all, we need to realise that just because something is preferred in a comparative experiment does not always make it better. Let me give an analogy here: If you serve two otherwise identical dishes, one of which contains more salt than the other, most people will favour the saltier dish. However, we certainly don't conclude from this that more salt in our food is always better!
TM-30 and colour enhancing products | SORAA Color Enhance
There are a variety of colour enhancing LED sources on the market, but as far as I can fairly judge the competitors' products, I have to say that I'm not impressed with what I've seen so far. In short, these products often have an unpleasant way of saturating colours while producing a pinkish hue of light. We are familiar with these lights from meat and sausage counters in various supermarket chains, for example.
No more pink-red islands of light, but consistent colouring with the same white point and yet the desired colour enhancement of the red tones for the counter display would be desirable. This is exactly what you can achieve with the SORAA Enhance Filter in combination with the SORAA Vivid LED.
