When HCl is added to a cobalt/cobalt chloride solution, it turns from pink to blue-violet, why?

Where does LeChatelier's principle say the shift happens? Would it be towards the right because: [Co(h2o6)2+ + 4Cl- <=> [CoCl4]2- + 6H2O. And since Cocl4 is blue, the solution turning that color would mean its shifting right, then?
