Unable to import colors from multiple Calendars

[Otaviotdp]

I'm tying to create a timesheet for my team, and so far I was capable of making my onw tab work, but when I try to import my colleagues calendar, everything but the colors column gets filled.
I already checked with him to confirm he indeed has the colors setup.
I'll be putting the link to a copy of the spreadsheet bellow, so you can check and see if it was a configuration error on my side. (the text for columns titles and so on is in a mix between English and Portuguese. If you'd prefer i could translate everything)
Spreadsheet

Thank in advance.
