Description for the background color in the microsite menu paragraph is not correct

[ddrozdik]

Test Environment:
Environment: | https://sandboxes-d9.openy.org/
Drupal version | 9.0.10
Open Y version | 8.x-2.7.1
Open Y installation type | Custom
Open Y theme | Carnation

Description:
When you create a new menu block using the Microsite menu paragraph, you can specify colors used to create a gradient background of the menu.

The description says I can select colors separated by a comma. However, these fields support only one value, and even if you enter more than one color separated by a comma while saving the block, the first one will be removed.

Expected result:

1. The description does not contain instructions about the possibility add color separated by a comma.
2. Fields do not provide the possibility to add more than one color per field.

P.S. To think about: why color field for the background is represented as an autocomplete field, while for the text color, it is a dropdown field? Both fields are designed to help choose the right color; however, they work differently. I think it would be better to unify the approach and have one type of field for both colors.

1. Description needs to be improved
2. Widget for the field - no consistency between drop-down and autocomplete. Drop-down makes sense but needs review from Ben - how it looks now and decide what would be better.

Add to conversation with Ben.
