The Design panel allows you to choose a background colour for the entire email as well as any block.
The Email Background colour choice is always available. Click on the colour swatch and select your chosen background colour from the palette, or type / paste the hexadecimal value into the box.
To change a Block Background colour simply select the block you wish to edit by clicking once anywhere inside it – this changes the outline from dotted green to solid green – then select your chosen background colour or type / paste the hexadecimal value into the box.
To remove a background colour, select the block you wish to edit and click the cross ( ) to the right of the colour field. Once you have done this the colour of the surrounding block (if applicable) or the email background colour will show through.
