For one-off experiences, the gallery or exhibition colours will be provided to you and should be considered, but overall colours for the digital interactive you’re working on should be discussed with AM.
In choosing background and text colours, the Material Design Colour Tool has an accessibility feature which can be used to check contrast and text eligibility.
Colours in digital products
The digital product suite uses grey and black tones which enables core products to be adapted to use in multiple settings. See Github for hex codes and colour application details.
