All day clock settings are accessed from the RecallCue app on your phone.
You can adjust the colors of both the clock information (time, date, day of week, and time of day) and messages text for easier readability. Each of these can use the same or different colors.
To adjust the colors of either the clock or messages:
From the home screen click on the menu icon in the upper left hand of the screen
Select "Day Clocks" from the menu
Click on the day Clock you want to edit
Find the "Custom Text Colors" option and toggle it on.
Click on the "Select Color" buttons and select the colors to use.
Click the Save button
