Do bass see colors?

[BassinBrits]

Deciding whether to buy red or green braid line got me thinking on this. Powerpro in their advertising reckon the fish can't see their red line?

I understood that fish see their world in shades of grey, like the old black and white television. I also believed that they see the colour red as being almost the same shade as black, which is more easily seen in their world having the most contrast to the background. I have definitely caught more bass on black and reddish coloured worms, but perhaps that's because it's the colour I use most of the time. lol's

Is it a grey world for the fish with reflective flashes or do fish see colors?
