What were Dmitri Mendeleev's favorite colors?

As a highly respected chemist and inventor of the Periodic Table, Dmitri Mendeleev likely did not have favorite colors in the traditional sense. Mendeleev's focus was on scientific research and the organization of elements based on their properties, not on personal preferences such as favorite colors. It is important to recognize Mendeleev for his contributions to the field of chemistry rather than speculate on trivial details like favorite colors.
