Hello and thanks. I've expereinced this twice now, but today is slightly different. I run iCal on all three of my Apple devices, using iCloud for sync. I find the color of the events is changing from the green to purple. I have not made any setting changes to do this, and last time in about 24 hours the events went back to green. Today I have the events that were booked by downoading the appointment remaining green, but all events entered directly are purple. I use only one "calender" in iCal (work) so I should not be seeing multiple colors. Thanks for any help!
