How to add type annotation?

[linonetwo]

Seems losing ways to type.

type DiffColors = 'white' | 'red' | 'green' | 'yellow';
const DiffRow = styled.p`
  background-color: ${styledProps(
    {
      white: 'white',
      red: '#ffedf4',
      green: '#f2ffde',
      yellow: '#feffe0',
    },
    'color',
  )};
`;
