I only see one color to change (tested in traditional and dynamic 
view). This color is used (in the default configuration) as the 
background color of the event bubbles.

Only when using it as a background color.

I tried to patch kronolith.js and it seems to work. Only when changing 
the color of a calendar, the rebuilt month view is built up with the 
"wrong" colors, but I think that I forgot some occurances in the .js 
file.

Concerning the colors: It seems to me that kronolith already changes 
the secondary color (the foreground) to black or white to match the 
chosen background color -- what makes the question of light colors 
appear nonrelevant as the other color will be chosen correctly.

But if you want to change this locally, this happens in the 
createEvent method in kronolith.js, just swap the .fg and .bg values 
for events with .al set, where setting the event's styles.

No, we already have far too many preferences in Kronolith to customize 
the UI, and I won't add another one that only works if users behave a 
certain way. This is really bad usability. When we add times (and we 
will add both start and end times) to the event bubbles, all-day 
events will be sufficiently distinguishable.

Hi,
As it would be a user-selectable option, it would be up to the user to 
choose colors which are readable.

How would that work with light colors that have too few contrast 
against the background? Opposed to Google we support arbitrary 
calendar colors.

Hi,
Why is it a bad idea to make this a user-selectable option?

In my case, my calendar view looks like this:

At the moment, this looks terrible in Kronolith but very well-arranged 
in Google Calendar.
Adding starting times would be a good first start (please no ending 
times, this would overcrowd this view!), but making normal events 
inverse would be a big advantage for me.

I could even do this just for me if I could get an idea where to look 
for this in the code.

Thanks a lot,
Anna Christina

I don't think that's a good idea, but implementing request #9866 would 
make them sufficiently distinguishable.

Hi,

I would like to propose an enhancement for kronolith:

In the dynamic month view, is it possible to have a visible 
distinction between all-day-events and events with a starting time?

In Google Calendar the all-day-events have a solid background color 
and the "normal" events have a colored text with white background.

Kronolith shows all events using an solid background and it is not 
possible to distinguish between an all-day-event and a normal event.

The best way would be to make this a user preference, together with 
the option to show (only) the starting time of an event next to the 
event text.

Thanks a lot!
