Custom color per event [$75]

[tobiasgraeber]

Hi,
is it possible to add an Option, to change a meetings color in the calendar?
(it is only defined by calendar-source colour as at the moment) ...sometimes there may be an important meeting and i want to make it stand out by red color for example...(without changing calendar). i think there should some color/Highlight function? any suggestions? maybe tags+a searchbox (filter) could also be great... #ux

Did you fix this issue? Go claim the $75 bounty on Bountysource.

Search is to be developed and tags is to be integrated some time too.

2016: I do not believe the ical standard has anything like this defined. Is there a precedence in another application? If so, how is that stored? I'd hate to see this implementation of the standard create its own island of unsupported fields.

2017: COLOR field! (sie comment by @georgehrke: #71 (comment))

Google calendar and Outlook have similar features, but they don't store it in the iCal data.
If we implement this, we would store it in an X-NEXTCLOUD-COLOR property

X-NEXTCLOUD-* is exactly what I would like to prevent when I say "island of unsupported fields".

[georgehrke]

Well, but there is no standard for it.

...how does Apple do this? 😁

[georgehrke]

Apple does not have the feature to color certain events.

One could try to bring a proposal forward according to this:

https://tools.ietf.org/html/rfc5545#section-8.2.3

   A property is defined by completing the following template.

   Property name:  The name of the property.

   Purpose:  The purpose of the property.  Give a short but clear
      description.

   Value type:  Any of the valid value types for the property value need
      to be specified.  The default value type also needs to be
      specified.

   Property parameters:  Any of the valid property parameters for the
      property MUST be specified.

   Conformance:  The calendar components in which the property can
      appear MUST be specified.

   Description:  Any special notes about the property, how it is to be
      used, etc.

   Format definition:  The ABNF for the property definition needs to be
      specified.

   Example(s):  One or more examples of instances of the property need
      to be specified.

I would also not go with COLOR as a property name, it does not reflect the fact that this is a very optional field. It should, for example, not storw the default color of the calendar in my opinion (if it did, you could never easily change the calendar color in the future without touching every single event). Using this property is - as stated in the title - more suitable to draw attention. I propose something like DEFAULT-COLOR-OVERRIDE or HIGHLIGHT-COLOR or something like that.

purpose would be "optional override to draw attention to a specific event or todo in a calendar. takes precedence over the calendars default color.

Value Type - probably just TEXT

Property Parameters - hex codes starting with # or named css colors (or do we need something else?)

There's CATEGORIES already, maybe supporting categories (and adding display rules to a category) would help the OP as well? This would stay well within the standard without the need for customisations.

example "oh hey, this needs to stand out for a reason" - the reason being that this is a familiy event. Add the category family. BOOM Family styling applied. Event stands out from the rest.
