These docs don't work!

I suspect the settings.php example is very old, from the D7 days. First, the variable should be $config for Drupal, not $conf. Next, the config keys are all wrong. This is what it should look like:

  default:
    // Multidev catchall. Value of PANTHEON_ENVIRONMENT = pr-9999.
    $config['environment_indicator.indicator']['name'] = 'Multidev';
    $config['environment_indicator.indicator']['bg_color'] = '#2e41a9';
    $config['environment_indicator.indicator']['fg_color'] = '#fff';
    break;
