The colours of surfaces in the room or dividers within the room must be selected in a way that prevents the colour of objects (e.g. a ball) and the background against which they are perceived from impairing perceptibility due to deficient colour contrasts in the visual task. Surfaces should be matt to avoid reflections of bright light sources.
Colour and reflective properties
Except for the case of television-appropriate lighting, EN 12193 does not stipulate any requirements for light colour and only minor requirements to colour rendering for the selected lamps or light sources. However, good colour rendering is highly important for the sporting experience of athletes and spectators alike. Fluorescent lamps and high-intensity lamps with a colour rendering index of at least 80 are common in sports facilities, particularly indoor facilities where light and colour significantly contribute to motivation, enjoyment and well-being.
In multi-purpose halls, light sources with good colour rendering are required first of all in order to facilitate faultless and quick recognition of floor marks.
