It seems, therefore, that Google wants the navigation through their creations to be much more intuitive with the inclusion of different color codes to differentiate the events that have been established. In this way, to know if there is a birthday of someone you know, it is as simple as checking if the color that has been assigned to that event appears on the corresponding day.
But the news does not end here, since Google Calendar also “suffers” a redesign of its user interface, as you can see in the image below. Now, the existing one is totally Holo, so it adapts perfectly to Jelly Bean and leaves behind the vestiges of Gingerbread (2.3) that existed in some buttons and, especially, in notifications. There is also a much cleaner and more comfortable way of seeing both the date and the watch and handling. By the way, the new update makes creating events and editing them much faster and easier.
Colors seem to be important to Google
With this update to Google Calendar, along with the one that began to occur yesterday in Gmail, it seems clear that from Mountain View they send a message indicating that the use of colors to access information will be an important part of their applications from this moment. The truth is that this makes the use of these much more intuitive, but if you have many events you run the risk that what you see on the screen will be like a collage. It will be necessary to verify the effect in its daily use.
This latest version of Google Calendar requires that you have a version of the operating system Android 4.0.3 or higher (although color codes can only be used if Jelly Bean 4.1 is available), otherwise they cannot be used. If you don’t have this development installed, you can download it in this link from Google Play.
