As it was defined in an IBM paper written in 1984. The term "immersion white tin" should not be confused with white tin / gray tin as in color. Even though the color is bright the term is used to reference the solderablity as stated in: Z. Kovac and K.N. Tu "Immersion tin: Its chemistry, metallurgy and application in electronic packaging technology". IBM J. Res Develop., 29, 726-734 (1984) Please look it up. If you need any other questions answered on the product let me know.
