Using colors in Agenda 15 for text, highlights, and backgrounds offers us new instruments that arise some reflections. As for colored texts and highlights, the use appears obvious, following the same we used for written notes on paper; I think it is a bit different for the background color.
Indeed, I am wondering if it is only a cosmetic option or if there is more. In my opinion, this new feature has much potential to improve our project organization and thoughts. If you use them randomly, you can obtain only a cosmetic result. On the other end, if you color the background of all your notes, it could be a nightmare because you could have too many visual stimuli. However, if you use this option more rigorously, I think you can get more.
For this reason, I decided to give one color to each of the four more used types of notes in my daily work: I use blue for the meetings, Green for Todos, Brown for the texts, and red for the notes directly related to the preparation of the projects. This way, I can immediately recognize the most important notes in my projects and the type. I believe this is a significant advantage.
The general logic of Agenda is to offer an app that can help organize your work as a flux, adhering more realistically to the mechanics of our thinking linked to the workflow. In that sense, colorful backgrounds can play an essential role because of the immediacy with which you can perceive them.
An improvement of this feature can be to indicate the colorful background of the notes even in the “table of content” in each project, On the Agenda, and Today. In this way, having a general look at it can give you the possibility to focus on the most important notes in a glimpse.
