Calendar Event Color

[Linus2]

In RFC 7986 iCalendar Property Extensions October 2016 a new COLOR property was defined. Currently, the event color in "VEVENT" is nor used as background color of the event.

Although it is only a MAY, it would be nice to have the events displayed in their event color.

5.9.  COLOR Property

   Property Name:  COLOR

   Purpose:  This property specifies a color used for displaying the
      calendar, event, todo, or journal data.

   Value Type:  TEXT

   Property Parameters:  IANA and non-standard property parameters can
      be specified on this property.

   Conformance:  This property can be specified once in an iCalendar
      object or in "VEVENT", "VTODO", or "VJOURNAL" calendar components.

   Description:  This property specifies a color that clients MAY use
      when presenting the relevant data to a user.  Typically, this
      would appear as the "background" color of events or tasks.  The
      value is a case-insensitive color name taken from the CSS3 set of
      names, defined in Section 4.3 of [W3C.REC-css3-color-20110607].

   Format Definition:  This property is defined by the following
      notation:

   color          = "COLOR" colorparam ":" text CRLF
                     ; Value is CSS3 color name

   colorparam     = *(";" other-param)

   Example:  The following is an example of this property:

   COLOR:turquoise

Thanks for submitting an idea to the Mozilla Connect community! Your idea is now open to votes (aka kudos) and comments.

This would be quite helpful.  It's frustrating to switch between apps and lose the color coding, or for someone you share a calendar with to not also share a color coding scheme.

Could we merge the different requests regarding event colors and category colors?
Because it feels to me that lots of people want the same.

Some want actual event colors as defined in the standard and that can be synced over caldav servers to other calendars.
And some try to use categories (and theirs) colors and make them more visible (instead of the little side bar).
But to my knowledge no other calendar app support the categories set by thunderbird and this information is thus lost when syncing calendars over a caldav server.

Thanks in advance for your feedback

I see certainly overlap between the requests you mentioned. I think there are two broad categories to group them in:

1. Supporting the color schemes that are used by standards/other mail providers so that the colors are synced and shown in thunderbird. E.g. what @Linus2 proposes in this idea.

2. Changing the way in which colors are shown in the agenda. Many people would like to see the event colored as a whole instead of just a colored bar on the side. E.g. what is discussed in https://connect.mozilla.org/t5/ideas/thunderbird-calendar-display-of-categorized-appointments/idi-p/...
