In India the phrases black money and white money are widely used to mean 'illegally earned money' and 'legally earned money' respectively. If you look up these phrases in dictionaries, you will not see them in any of them because such phrases do not exist in real English. The word black and white collocate with tea and coffee (we can say black tea or white tea) but they do not collocate with money. 

Likewisewise, Indians drink strong tea and light tea. Strong tea is used in real English as strong collocates with tea but light tea is not used in real English as light does not collocate with tea. What Indians call light tea is known as weak tea in Britain and America.
