Fixed! I just updated Baikal to 0.4.5. In that version card and cal are combined in a single endpoint. So no need anymore to configure any redirects.
For reference and transparency: We have created this report on Apple Bug Reporter on 23 Feb 2016 here: https://bugreport.apple.com/web/?problemID=24791895
When creating a task list with MKCOL/MKCALENDAR, the calendar-color is ignored.
Steps to Reproduce:
The task list should have the color from the MKCALENDAR request.
The color from the MKCALENDAR request is ignored and the task list is assigned a random color.

This DOES work for calendars with supported-calendar-component-set set to VEVENT only. It doesn’t work for task lists only.
