Hi Granite and Airmale,
Thanks for your feedback. Your info was for me a confirmation of what I thought the colour could might be: Perl White RAL 1013.
How are you as tensions are becoming huger now in your country. I really do not know where everything can lead to. I hope everything will be over very fast. I'm fine and within 5 weeks from now my new Air Holland livery design will be implemented on the PH-AHF Boeing 757-200. I'll keep this forum and you updated.
