Range Rover Interior Leather Colour

Can anybody tell me how to get the right match colour for my 2007 Range Rover Sport. I am looking for a touch up leather paint. The colour is creamy but when I ordered cream it was too light, I added other colours but still can't find a match.It states LRC 798 on the plate but I cannot find the actual name of the colour.
Thanks

Lrc 798 is zermatt silver, Ivory , Windsor or cirrus ? Ivory is cream, Windsor is a faun tan, cirrus is silver grey
