Be able to define a custom color (e.g., hex code, color wheel, hsv) for each calendar. Or at the very least increase the number of options to include a range of saturation (i.e., muted to vibrant). The current options are limited to 9 colors, all of which are vibrant. These are too colorful and I am used to creating more muted colors (i.e., Google Calendar).

I am a freak perhaps in how I use calendars. I am currently requiring MORE colour options, for instance, you could allow the entire colour palette/spectrum so users can choose colours for different calendars.

I do my best with what's available, and I support the already voted up post proposed by Carolyn about allowing us to set colour events (ref: https://feedback.titan.email/calendar/p/event-colours)

My request is about calendar colours. In general, Titan could get ahead of competitors if such creative workflows were possible. I love Titan, and I am sure you get a lot of requests daily, and I feel empathy for your hard work.

You do listen to us, and constantly make improvements. For that, I am grateful, and I am also sorry that I often propose more features. However, I think this proposal would be beneficial to many.
