Fabric dye will also work, but it often has to be heated first, depending on type, I have no idea if that could be sprayed. I don't think a new cloth is that bad, after a time it will collect dust, and dirt, just like the old ones did. In some cases I think that the dull colour may be attributed to tobacco tar as that was a popular pastime back in the 1930s and 40s.
