Gelcoat finish info needed for Laser Performance 2013.

Hi all,
I have a 2013 Laser Performance and I did a couple of small nicks on deck. It looks just a tad Grey or a minimum tint of blue compared to a bright white?
Does anyone knows what is my best bet to buy a small amount of gelcoat to refinish it? Brand recommendations?
See pictures attached.

Thanks!
Martin.
