Sensory marketing is based on directly impacting the senses of a potential client and evoking the desired sensations. To a large extent this refers to the subconscious. During the initial 20-30 seconds of contact with a new place or product, the senses absorb multiple stimuli. There is so much information that only part of it is intentionally registered. However, the subconscious constantly analyzes the message, creating a holistic image.
Illumination is the only form of light that does not characterize the light source itself, but the brightness of surface illumination. The unit of illuminance in the SI system is lux (lx) equal to lumen per square meter (cd • sr • m-2).
The color temperature is determined by comparing the color of light emitted by a given source, with the corresponding color of a black body at a given temperature. The curve presenting the black body radiation is shown on a chromaticity diagram.
The PN-EN 12464-1 standard introduces the following ranges and formulations when determining the color temperature:
Color rendering index – in order to ensure proper color reproduction and color contrast, light sources with a high color rendering index should be used. Then the presented objects are presented in their natural, unadulterated colors. The color rendering index, referred to as Ra (CRI), has a maximum value of 100. It provides information about the extent to which a given light source allows color observation.
