The design is aimed at maximising information. That's why things like the date are a different colour. The temperature text changes to a different colour according to how hot it is. The background changes from blue to red according to the weather. The Colour change temperature range is 20°c to 35°c. The 4 layers to adjust are the red layer and the 3 temperature text layers if you want to adjust the temperature triggers. There is a version of this that goes super dim between 10pm-6am called UzeWatch The Sleeper. http://facerepo.com/app/faces/details/uzewatch-the-sleeper-14a48d75749, 12h Time, Battery Level, Calendar, Charging Status, Date, Phone Battery Level, Phone Charging Status, Weather
