Q: Calendar color keeps changing:

Same here.  The seemed to be resolved by late morning a week ago today.

My calendar colors are not changing anymore. It seems that the problem had been fixed in the last days.

It looks like the issue is occurring again. My calendars started again to change colors some hours ago.

Anybody else noticing the same problem?

Yes it is happening again...

Same here - This morning 2 purple calendars and one blue.

Can only change the colour of "Calendar" - work and holiday cannot be changed in browser.

Please fix it.

Yes, happens with my calendar as well

Same here.  Work calendar defaults to purple and the home calendar defaults to blue, just like the last time this happened back in August.  It would be wonderful if Apple could resolve this issue forever.

Yep, same here...

My Work Calendar changed colors today on my iPad but not on my iPhone.  Won't stay the color I assign.  Very frustrating.

Yep same, just had it happen to mine.

This is happening to me and my business as well. INFURIATING. The color codes are the bases of our departmental schedules and controls for our work schedules, and school assignments. IT"S ALL COLOR BASED, and this has virtually SHUT US DOWN. It's clearly happening a lot, it's happened before, and APPLE NEEDS TO STOP SCREWING AROUND WITH US LOYAL CUSTOMERS repeatedly. It's not enough that iOS7 is such a shock and features shifted moved etc (for our own good as always, bs). FIX IT.

Happened to me, also.

Happened to us too. This is really irritating. It is impossible to manage multiple calendars if the colors are not different.

same here... it is super painfull

Yes here too, all my custom colors have reverted to defaults and they are refusing to change.  Appears to be an icloud-based problem if it's happening to so many people on the same day.
