There is more than one hydrate. If you are dealing with the dihydrate it is CoCl2 2H2O than it is blue (sorry but the keyboard won't let me put the 1st and last 2 as subscripts nor allow the dot between the two "2"s, similar to the dot used when you multiple 2x3=6 and don't want to use the letter x. This is what is used to make the test strips we give in labs. If you are dealing with the hexahydrate it is CoCl2 6H20 and this is seen as the pink colour of the test strip once exposed to water.
Cobalt (II) chloride = CoCl2
