Google Calendar Adds 200 Custom Colors and a Full RGB Picker

Google Calendar is expanding its color system: the default palette increases from 11 to 24 colors and web/API users gain an RGB color picker allowing up to 200 custom colors. The picker is available on web and via the API (mobile shows the larger palette but cannot create custom colors), the feature is rolling out gradually with no cost to users, and colors created on web sync to mobile. The article frames this as a visual improvement useful for power users and notes it is part of broader Calendar updates.
