ACF Multi-Select Field Outputs a Random Comma

Hi,

Using the following code from the ACF Select page (https://www.advancedcustomfields.com/resources/select/);

<?php
$colors = get_field( 'color' );

// Create a comma-separated list from selected values.
if( $colors ): ?>
<p>Color: <?php echo implode( ', ', $colors ); ?></p>
<?php endif; ?>

Why am I getting a comma if there is only one option selected?

I had imagined it would only show commas to seprate options.

It should not be displaying the comma if the array only has a single value.

Is the code in the OP the actual code used or is this just copied from the link you provided?
