Q: Calendar color keeps changing:

I have the same problem.  It seems that the Home calendar now has an unchangable default of Blue and the Work calendar is now an unchangable default of Purple.  It will allow me to change these two calendars back to my old color scheme of choice, but after a few seconds the color is changed back Home=Blue and Work=Purple.

The same is happening to me. I used to have four calendars and each of them had a specific color. iCloud syncing had been working perfectly till some hours ago. Now calendar colors keep changing: I have tried to reconfigure colours both on iCal and iCloud, but without success.

My system has OSX 10.7.5, up-to-date.

Seems to be fixed now. Suddenly, my calendar colors have returned to the way I had them set up.

My calendar colors were restored to correct configuration some minutes ago, but then they were mixed-up again. I guess there is some kind of "bug-fixing" activity going on behind the scenes...

Yep.  Same thing is happeneing to me.

Since this morning the same thing is going on between my home and work calendar. It's not any better yet at this point. Somebody from Apple with some suggestions?

I am having the same issue. I have shared calendars with my family. I change my calendar colour back to what it was and it just changes back.

I hear advertisements from the new Job's movie "about the little things". The little things are what has been aggrevating lately. Getting errors when sending emails (connection) and now something as simple as calendar colours changing. Apple needs to get their S**T together.

Same problem here, it currently affects my Macbook, and sometimes it fixes itself. Does Apple work on fixes and apply them in a way that I won't be aware of?

I am having the same problem here, it is really annoying!!  Now my wife and I can't figure out who's appointments are whose cause all of her appointments are turning the same color as mine.  Apple fix this please!!

I don't know if it influences Apple to have more complaints here, but I am experiencing the same problem.  This is the only online comment I have found relating to it; it seems clearly to not be the user's fault.

I have been having the same problems. They started last night. The colors on my iCloud calendars keep changing back to blue and purple and won't stay as I had them before as green and yellow. I even tried changing them on the iCloud website, and they still reverted back. My husband and I have the same iphone 5's and his calendar seems to be fine, colors stay the same for him. There must be a glitch. Hopefully they will fix this because I have multiple email accounts on my phone and with the majority of them defaulted to blue is just confusing.

I support a number of customers who use iCloud calendars for their business and the colour changes are causing real confusion amongst the staff who rely on the service for their schedules.

Come on Apple - sort it out please, or at least let us know why it's happening!

Ok, since a couple of days my iCal colors are stable again. I think Apple solved this mystery. How are your iCal's doin'?
