A colour photographic recording material having a support, at least two blue-sensitive, yellow coupler-containing silver halide emulsion layers of differing photographic sensitivity, at least two green-sensitive, magenta coupler-containing silver halide emulsion layers of differing photographic sensitivity and at least two red-sensitive, cyan coupler-containing silver halide emulsion layers of differing photographic sensitivity, characterised in that the silver application rate is less than 3.2 g of silver per m2, camera sensitivity is at least ISO 100 and wherein, when an exposure is made of a grey card of density 0.6 with fluorescent light of light colour 21, the recording material gives rise to a hue on the print which, in CIELab values, meets the conditions a>0 and 0<b<30, if the photograph exposed with daylight is at a=b=0 with the same print filter pack, is distinguished by improved colour reproduction and in particular by a reduced green cast on exposure with fluorescent light.
