setting values if they don't already exist

What's the best way for setting values if they don't already exist in PHP?

Is it safe to use

$color = $option['color'] ?: 'blue';

Instead of

$color = isset($option['color']) ? $option['color'] : 'blue';

Or there's a much better way?

In PHP 7 you can now use the Null coalescing operator:

$color = $option['color'] ?? 'blue';

This is the same as this in PHP5:

$color = isset($option['color']) ? $option['color'] : "blue";

Both are the same, but $color = isset($option['color']) ? $option['color'] : 'blue'; prevents a PHP Warning exception
