Hello everyone, can someone help me here. I just bought a manhole new wide screen NH 103. The back colour appears to be a strange shade of blue when seen under natural light. It appears to be dark blue with a light tinge of dark green, instead of the marine blue colour seen on the box. Can anyone here with manhole tell me whether this is normal?

For reference, I refer to the website www.pantone-colours.com . The back colour of my manhole is PMS308 instead of PMS300. Please help, thank you.

Daniel
