Color support in acf-(composer) blocks

In MyBlock.php

public $supports = [
        ...
        'color' => true
    ];

Or more fine tuned:

public $supports = [
  ...
  'color'  => [
    'background' => true,
    'text'       => false,
  ]
]

The plan itself was posted on Twitter. It is a bit old, but it sounds like decent approach

Level 1

Style the editor and core blocks to match the client theme.
Disable custom colors & fonts to keep the client on brand
Disable all core blocks your client doesn’t need per post type. Too many options are confusing. (Optional)
