Natural Colours through Good
Colour Rendition
Daylight gives the most natural colour
reproduction, making colours look
fresh and lively, which is crucial for
man's visual performance and
well-being. Likewise, fluorescent
lamps with a colour rendition rating of
1b for economic office illumination
make the lit objects look fresh and
lively and people look attractive and
healthy.
