Probably not really a spoiler, but

Water sailing times:

Lightest blue: 6 secs
Light blue: 2 minutes
Blue: 14 minutes
Dark blue: 1 hour
Darkest blue: 3 hours

I think I got it right, but I am usually asleep when I aim for the the darkest blue sailing .

Please correct this if I am wrong!!

 

hmm interesting.. Cant double check since my lads are on a exploration voyage, but it looks good

 

is there any red color?

 

Only after a completed voyage

 

What's the name of the darkest blue? Plus Blue is 15 minutes.
