Semantic colours for feedback
Also common between brands, the semantic colours are made to add meanings to components, to enhance feedback to the user. This set of colours is used for action buttons, alert messages, and form elements. Input fields, for example, may contain positive and negative feedback, whereas alert messages may provide feedback or warnings.
Background colours are usually used when creating sections in your designs. Few backgrounds are provided and if you use other shades please share this with us.
Other palettes can be used in data visualisation, for color chip tags, etc.
