[Evolution] Coloration in Evo 1.5.9 calendar

[Trey Sizemore <trey fastmail fm>]

I thought I remember seeing somewhere that the 1.5.x series of Evolution
had the ability to assign colors to various items in the calendar
(personal items = green, meetings= orange, phone calls = yellow, etc.).
I've played around with the settings, but can't find this.  Was I
dreaming?
