There MAY have been due to the oxidation of the chromous salt.

Explanation:

$[Cr(OH_2)_6]^(2+)$ as far as I know is a beautiful blue salt. In solution, partial oxidation to $[Cr(OH_2)_6]^(3+)$ occurs which is red-violet in colour. So the colour you see is the result of $Cr^(2+)(aq)$ and $Cr^(3+)(aq)$ ions..........
