Within the StoreCore’s corporate style, Material Design (MDL) is used for all communication. Higher contrast. Harder colors. Compact text formatting.
Green + Blue is the main color.
Green-A + Blue-A is the accent color.
In addition, you must, as in the typography, always deviate at least 2 steps. For example, 200 + 400 goes together, but 300+ 400 not.
