Q: Colors changed on their own!

Yup I have the same issue and very annoying because I keep multiple calendars for my work. Do you think Apple are aware?

Just another input to say I'm having the exact same problem all day today.

No help here, but another predictable characteristic (for me). If I refresh my iPad or iMac the random purple color reverts to my chosen color. However, it will revert back to purple at random. It's got to be an (annoying) iCloud issue. One other weirdness -- I lost all my scheduled dates on my iPad and had to do a hard shut down and reboot to restore the schedule. Nothing weird on my iPhone yet.

Update - still randomly changing back and forth. When I click on the Calendars button in the upper left-hand corner the correct color is displayed for each of my calendars. Unchecking and then rechecking the box puts the correct color back on the calendar - not the Purple that iCal thinks is every color today. I'll see how long it lasts.

Yup, me too...green work cal on iCloud on all devices keeps being changed to purple...CAN SOMEONE FROM APPLE PLEASE GET ON THIS AMD GICE US A DARN FIX?!?!?!?!?!?!!!!!!

Typically apple so slow in responding to their loyal customers...sigh...I'm beginning to look at samsungs guys!!!;-(

iPad predictive text..annoying too.... Should read AND GIVE US A DARN FIX!!!!

Plllllllease.....sooon!?!?!!!!!

Seems fixed to me. Anyone else?

Hasn't happened in last few hours.

Crossing my fingers.  I think mine is fixed as well.

All's well for the past couple of hours.

Yup, mine too seems okay and stable at last rather than doing the chameleon shuffle....wait and see....nice of Apple to,explain to us of course...;-)

Still...tomorrow is another day and maybe another colour...good luck all.

When I try to change the color, it changes, then changes back to the original one.

Anybody else finding this happening agin today?

Yup!!!;-(

Here we go again. Well done apple,another bug well sorted...how much are you worth again...iphone5s or c was about to be ordered,but perhaps it's Samsung time. Get the basics right!!

I'm afraid so. Problem is back
