It's probably not a copyright violation because it's too simple, and not a trademark violation because it's for a different sector. Hence, just "bold choice".

It's probably not a copyright violation because it's too simple, and not a trademark violation because it's for a different sector. Hence, just "bold choice".

It was immediately recognizable to me as another brand, and that's not what you want for your logo.
