New Futura with slight deviations in the bottom colouring

[Magicmullet]

Hi there.

I am one of the first lucky ones to receive a new futura (122, Technora) in Finland. However, being quite new to the sport and the equipment, I'd like to know, whether it is normal that the bottom of the board is not uniformly white. I mean, there are some spots that have a slight greyish tint, and these seem to be a result from the finishing of the bottom form (i.e. sanding or some other technique used). This board is brand spanking new, just unwrapped from a ton of cardboard and bubbled plastic.

What would be your thoughts?

Cheers all.
