I'm using iCal for managing my schedules in my company. And my company is using Microsoft Exchange server for schedules. When I added the company account to iCal, it set the calendar color as orange. I have been using blue for my working schedule. So it's confusing me so much!

Usually, other accounts support changing the color by clicking Get Info menu. But this Exchange account doesn't show any configurable options. How can I change the color?

I think this issue is specific to Lion. You can't even get to the info screen for an Exchange calendar, to make the colour choice shown in the screen shots here. Googling, I turned up the following Applescript to accomplish the task:

tell application "iCal"
  set color of calendar "Calendar" to choose color default color {0, 0, 0}
end tell

This works like a charm! – Eonil Dec 16 '11 at 9:16
The script works, but how do we change color of delegated calendars of the same name? – erotsppa Jan 16 '12 at 21:28

I'm running Snow Leopard and my iCal Get Info command allows me to change colors. Here's a screen capture where I can make this change.

To reach this window, I highlight the exchange "Calendar" in the left hand sidebar of iCal and enter Cmd I.

In my iCal setup, I have "Home" (orange) "Gmail" (blue)and "Exchange" (red). I can get info and change the color for any of the three calendars. In my list, I have "Home", "Gmail" and "Exchange". Here is how 2 appts look:

What do you see when you get info on your exchange account?

This shows the color panel for calendars on other accounts, but not for Exchange account. – Eonil Dec 16 '11 at 0:58
This is for my exchange account. In my setup I have Gmail and exchange. In either one, I can get info and change the color. – bg2011 Dec 16 '11 at 2:28
I pasted in an example in my answer above. – bg2011 Dec 16 '11 at 2:40
Doesn't do it! I tried right clicking and selecting Get Info... and every other calendar gives me the dialogue box you're talking about. Exchange calendars give nothing. – user18686 Feb 13 '12 at 15:53

After the recent Lion update, the color issue is resolved by right clicking on the desired exchange calendar, and selecting Get Info. A color combo box is now available. Prior to the update, only iCloud or local Calendars would allow color change in Lion.
