Cobalt is known for blue colouring: cobalt silicate and cobalt(II) aluminate (CoAl2O4, "cobalt blue") provide a distinctive deep blue color to glass, ceramics, inks, paints and other substances. Cobalt was added to the glass to protect the liquids it might contain from damaging light rays. (Image courtesy of Jurii, Creative Commons Attribution 1.0 license.) But like its sister transition metals, cobalt can assume a number of beautiful colours besides blue.
Blue- well yeah blue but a lighter blue. It depends on how much white you put in... :)
Some household items that may contain cobalt include rechargeable batteries, blue pigments in ceramics or glassware, and certain metal alloys used in kitchen utensils or appliances. It can also be found in some paint or in trace amounts in stainless steel cookware.

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.
its like a glass but put the glass in 6 squares make it like a square ok?
When blue cobalt chloride paper comes into contact with a mirror, it may change color due to moisture. Cobalt chloride is hygroscopic, meaning it absorbs water vapor from the air. If the mirror is cool enough, condensation can form on its surface, causing the blue paper to turn pink as it absorbs the moisture. This reaction demonstrates the paper's ability to indicate humidity levels.
its a blue flag and a glass of water
