As a user I want the app to have a coherent color set

All of the screens should use a coherent color set defined in the model

ToDo

• Create date structure for color set (?)
• Create a member in model containing the selected color set (static for now) (?)
• Alternative: Use system color sets
• Make all screens use the models color set

Acceptance Criteria

• All screens use coherent color sets
