It seems some of your project have a Color that is not in Hexadecimal format (#XXYYZZ where XX, YY and ZZ are hexadecila values).
This should not happen if color is defined through project screen.
It may happen if color is defined through import or API (or direct DB update, but I hope you did not do that 
)
Check colors for your project.
Please fix any invalid format or report any valid format that generates the issue.
