A suitable range of colour temperature lies between 2000 K and 6500 K for outdoor facilities and 3000 K to 6500 K for indoor facilities. Lighting systems used in combination with daylight should have a colour temperature close to that of daylight. A camera system can only adapt to one colour temperature at a time. In addition the preferred photographic films for sports usage are daylight balanced to around 5500 K. As can be seen in figure 3.6.A daylight conditions during late afternoon periods is around 5000 K. Recommendations on preferred colour temperatures for both non-televised and televised events can be found in section 4 of this guide Colour rendering.3.6. B Colour rendering (also called Ra) describes the capacity of a light source to faithfully reveal and reproduce the natural colours. Colour rendering is ranked on a practical scale from Ra 20 to 100. Where the higher the index the better the colour accuracy. The degree of colour accuracy of a sports lighting system depends upon the purpose of the installation. For instance, recreational activity is less demanding than that of televised events where promotional materials must be reproduced accurately. High colour rendering contributes to the quality of
