Best canvas colour for damp/mould resistance

I'm having some new canvas work done, and rather than try to match the red of my sprayhood, I've decided to go for a contrasting colour.
I was thinking cream/beige, the canvas maker suggests that grey is less susceptible to mould.
Anyone else in a damp Northern climate have any recommendations from experience?
 
I don't think it makes any great difference, unless you want to choose black or navy blue. Treat the fabric twice a year with Boracol 5RH and it'll stay like new for years.
 
I have beige covers which have lasted for many years. The trick is to give them a wash at the end of the season - put them on aline outside and give them a good hose and a wash with laundry detergent. Then coat the fabric at the start of the next. I've found that Fabsil works fine. I do use Boracol but only on timber as it is expensive.
 
Thanks folks!
Maybe "resistance" was the wrong word, more what shows up the green worst! I'll choose which one looks best alongside the existing sprayhood.

I do clean the canvas in the Spring, last year I used fabric paint to restore the redness which worked a treat, then a couple of coats of Fabsil.

I was wondering why you get so much discolouration while I get none, and then I saw where you hail from! I think that if you treat with Boracol/Patio Magic a couple of times a year you should be able to suppress it adequately. Another policy is to use an old sprayhood for the winter, as we do, cockpit tent also

It's a cockpit tent I'm having made - it's going to stay up during winters afloat, so it'll be wet a lot of the time!
I'm resigned to the red sprayhood fading and being restored each Spring, I hope the new grey/beige tent will hold its colour better.
 
Not Rassy silver that's for sure!

The basic Rassy canvas is pretty flimsy actually, and is cheaper to buy from Ellos than to seek out here. We are though on our third sprayhood in 20 yrs, but I am preserving my current one by taking it off in winter. On the other hand, it doesn't seem to get green, or go mouldy except for the stitching, perhaps because it dries quickly.

It's not really mould that we get here, it's a special green thing that I suspect would turn into moss given a couple of months!
I spent Sunday scrubbing it off the decks, now they're covered in snow instead.
 
I live on the west coast of Scotland and used to have trouble with green canvas work and decks until I read about Patio Magic on here. Spray hood fifteen years old and no green or black spots, restiched twice though.
