Does anyone know of any sets of surface colour spectral reflectance curves in the visible light region (i.e. from 400nm to 700nm) available online?

I think there are physical limitations on the spectral reflectance curve that can be achieved by a physical object. The small number spectral reflectance curves I have found online seem to share...
