The colours used in the add-on(s) are a "close" match and best approximation of the film overlays. With screens there are some limitations that prevent a full implementation being put in place. Certain constraints such as the brightness of the screen and the environmental lighting will also have a significant impact. It is therefore important to note that this add-on(s) for Google Apps has been created to assist those who might benefit from changing the colour of their background, by simplifying the process. With the add-on(s) installed it is possible to change the background of any document they have created or been provided (via Google Classroom for example).
Extore is a team of professionals who are passionate about creating extensions for web browsers. This devotion also gives us opportunity to appreciate work of other people. We get inspired by useful, open source extensions made by developers all over the world. Our strong belief is that one should share helpful add-ons with others. That’s why we’d like to present you our ever-growing list of favourite extensions that have inspired us. Moreover, as you probably have already learned, sometimes struggling for the best brings an end to the good. Talking about add-ons it often turns out that an upgrade is worse then previous version. Also it can become really tricky to get back to the beloved version of your favourite extension. That’s why we’re going to make not only the latest, but all versions of our favourite (and we hope yours too) add-ons available for download. No more compromises, just stick to the version you really like!
