Retrieve a value from an array and make a condition

I have the following code that I am using on WordPress:

if($terms && !is_wp_error($terms) ) {
  $colors = array();
  foreach ($terms as $term) {
    $colors[] = '\'' . $term->slug . '\'';
  }
}

print_r(array_values($thePack));

The variable $color now is a basic Array, which print_r displays like this:

Array (
    [0] => 'white'
    [1] => 'green'
)

I'd like to make a condition in order recognize whether the array has or not a specific value, for example:

if(in_array('white', $colors) {
  echo "This is white";
}

However, it is not working at all, because the in_array does not recognize the value in the array!

How could I make the condition work?

The problem is you are escaping the color into the array. Instead of using

$colors[] = '\''.$term->slug.'\''

Just do

$colors[] = $term->slug

And when you output the slug to the web page or the database, then you escape it.

Why not do something like this:

while(list($key, $value) = each($array)){
    if($value == 'white'){
       echo 'this is white';
    }
}

Your array values (the color names) include single quotes, which you need to include when you search for a value:

if(in_array("'white'", $colors) {
    // ...
}
