You can choose and customise the background colour and text colour for your template blocks from the dynamic settings.
See also: Set background and text colour for template blocks
Note: You can only customise one colour for background and one colour for text per block, even if the block has multiple elements (e.g. a two column text block).
Note: If your block has HTML which already specifies a background colour (e.g. background-color, background, bgcolor), this may overwrite the colour you set. Simply remove the hex code from your HTML script to use the colour picker instead.
You can either choose an available colour, or enter a hex code.
You can also click +Save colour on any colour you choose and use it for other blocks:
When you save a colour, it will only be available to you (not anyone else on your team) and only as long as you do not clear your cache.
