Fri, 10 Apr 2026 02:21:31 +0000 https://bugs.horde.org/ticket/7480 Switch to colors by calendar instead of colors by category The current implementation of calendar coloring only takes into account the category of an event. All Business events, for example, might be red while all Pleasure events might be blue. This is a great feature, but is lacking in a shared calendar environment where one might be displaying a dozen calendars on the same page all containing events on the same day, some of which might even be of the same category. Currently, the only way to determine if something is on one calendar as opposed to another is to disable and re-enable calendars until the event disappears and re-appears. One can mouse over the event to find the owner, which is helpful, but even clicking on the event doesn't tell you what calendar it belongs to. I'd like to request that we start working toward a system similar to how categories are colorized but that enables colorization by calendar if requested. Perhaps the calendar can be denoted by the border color rather than the background (though it seems the opposite might be more appropriate in my opinion.) Either way here's an initial patch that simply adds a hash of the calendar name to the class on a given event so that administrators if they wish could add colorization to a css file as a stop-gap fix until something more robust can be developed. Sun, 12 Oct 2008 13:10:00 +0000 https://bugs.horde.org/ticket/7480#t49627 We do need this option eventually. I am opposed to having colors for _both_ categories and calendars, since right now I don't see a good way to visually present that. If someone can come up with a clear way to do it, then I'm open to it. Assuming that we also allow for multiple categories for calendar events (or tags - same concept really), then it may make sense to switch entirely from color by categories to color by calendar, since multiple categories would present the same visual problems - how to represent multiple colors for a single event without the calendar turning into a tie-dye shirt. At the least, I think we should have an administrative option so the sysadmin can set an install to be colored by either categories or calendars.

Sun, 12 Oct 2008 16:14:57 +0000 https://bugs.horde.org/ticket/7480#t49631 I thought I remembered that, but didn't see it on the task list. Any specs on how they want it to work specifically? Sun, 12 Oct 2008 16:18:05 +0000 https://bugs.horde.org/ticket/7480#t49632 Here's Sunbird's solution. The blue is the calendar and red represents the category. This could be easily duplicated with a border-right: 5px solid red; If the events weren't rounded. It looks a bit funny when they are.

They just want colors per calendar, so I was thinking of adding that configuration switch to either enable colors per calendar, or per category. Sun, 12 Oct 2008 17:32:56 +0000 https://bugs.horde.org/ticket/7480#t49634 FWIW, I think that since we are moving to a tag paradigm here instead of categories - which means we can have multiple tags per event, as well as mulitple tags on the calendar the event belongs to, it will be a better idea to just move to per-calendar coloring instead of having to deal with how to color an event based on tags. Would avoid issues such as what color gets applied when multiple tags are present on an event - does the calendar tag get applied if the event has no tag etc... Sun, 12 Oct 2008 17:44:08 +0000 https://bugs.horde.org/ticket/7480#t49635 My instinct is the same as Michael's. We're going to be allowing multiple tags, or multiple categories, soon; events will never have more than one calendar. So calendar seems like a better thing to visually differentiate on. Sun, 12 Oct 2008 17:46:11 +0000 https://bugs.horde.org/ticket/7480#t49637 Elliot - any idea what Sunbird does with multiple categories or tags? Sun, 12 Oct 2008 17:47:12 +0000 https://bugs.horde.org/ticket/7480#t49638 It appears that Sunbird only displays a color for the first category. All categories are maintained in the ics file, but oddly only the last category shows up in the edit event dialog, which only supports one category per event. Sun, 12 Oct 2008 18:40:18 +0000 https://bugs.horde.org/ticket/7480#t49639 I'm convinced now that category/tag coloring doesn't make sense anymore. Sun, 12 Oct 2008 23:46:57 +0000 https://bugs.horde.org/ticket/7480#t49646 adjusting the ticket summary accordingly Mon, 13 Oct 2008 01:53:18 +0000 https://bugs.horde.org/ticket/7480#t49651 We might be able to head off some of the bad reaction to this if we could create a reasonable implementation of "sub calendars". I'm not suggesting any nesting other than a single parent/child relationship. But by allowing a user to group a few different calendars (which would be available as separate ics/webdav items) under a single Share - i.e., all getting the same permissions; allowing users to subscribe to calendar "bundles" all in one instead of dealing with however many calendars I have; and by letting users choose colors for each sub-calendar, we might retain some of the best of both worlds here. If you look at a program like iCal, you are basically encouraged to create multiple calendars to do any colorization or category-like differentiation. We could do the same thing, but simplify the calendar creation process a bit and the share overhead by nesting the sub-calendars. Mon, 13 Oct 2008 02:28:24 +0000 https://bugs.horde.org/ticket/7480#t49655 Also, whatever model we settle on here should, in my opinion, also be applied to Nag and Mnemo. Turba is as usual its own kettle of bats. Mon, 13 Oct 2008 02:28:52 +0000 https://bugs.horde.org/ticket/7480#t49656 Don't remove colors by category, keep colors by calendar optional as suggested by Jan in comment #6. Our use case for Kronolith is a small office with multiple calendars for ppl. taking appointments. We have 5 - 6 categories for the different appointments so it's easy to see if we can take more than one appointment for a person at the same time (depending on category) or if e.g. the person is out of the office. Guess this is a many categories vs. many shared calendars thing. Maybe it's better to create an option to display the calendar name below an event like it's done for a location. Or for the category - which would be a good enhancement of the print version. Color printers are rare, most ppl. use black & white for printing and you can't distinguish the categories on the print out. Our categories are centralized in the config file and locked. If a there's still an easy way to provide the same categories for all calendars in the config, then i guess i'm ok with this.

The main issue here is that categories are turning into tags - which are essentially the same. The difference will be that calendars will be able to be tagged with multiple tags, and so can the events the calendar contains. The problem with keeping a per-tag-color implementation is how to handle the coloring when an event is tagged multiple times....and how to handle when a calendar and the event are both tagged, which color should take precedence etc... To sum it up, events can have multiple tags, but only ever one calendar - so it makes sense IMO, to color per calendar. If you have any ideas as to how to represent multiple tags with colors without the calendar looking like my 5 year old's crayon box, feel free to share :) I *do* think the point you bring up with having your categories pre-configured is a good one - I'm sure there are many people using it in this way, not sure yet how to go about satisfying that use-case with tags... Tue, 03 Feb 2009 14:25:14 +0000 https://bugs.horde.org/ticket/7480#t52246 This has been implemented in Git. Tue, 03 Feb 2009 18:56:24 +0000 https://bugs.horde.org/ticket/7480#t52248 Because my organisation quickly needs colors per calendar, I used the ideas mentionned here to create a patch for horde webmail edition 1.2.4 to display colors in the Sunbird way. It will maybe interest some people so I share it here. For now, the colors are generated from the name of calendars owners but we plan to make them customizable.
