Blue and white light ratio

          I am going to purchase a new 120 watt Led light system and want it to be able to grow anything from softies to sps corals. I like my tank looking more blue so I was wondering if a 2 blue: 1 white ratio would still be good to grow corals well or if i should stick with a 1:1 ratio. Would it matter? Which color light is more responsible in growing corals?

2 to 1 would be just fine that's what I did on my led and that's what I see a lot of people doing
