Hi Yedaoxiang:-

I am sorry but your questions are very unclear.

I have no idea what you mean about “orange” whilst you are displaying the attributes of a cheese collection.
Orange can mean a fruit or a colour, and has little do with cheese.


Can you say clearly what you are trying to do?


You cannot download the raw spectra unless you have a Reseacher licence. Most people will NOT find the raw spectra helpful.


Consumer Physics provide the Cheese collection as an example. You can copy the structure to a new collection and make your own either for cheese, or by changing the attributes for other materials.


The advantage of cheese and similar dairy products is that you can use the values from the nutritional information on the wrappers. This is good enough to learn the ideas, but totally bad for a real model – because those values will be rather inexact.
