New idea help needed--toggle pattern lighting

So here is an idea…I have 2 led lights for my fish tank with a 3 way switch on them and 1 power source per light. So it is on off on. one setting turns on all the led’s and the other way is to just have the blue led’s for night time. What i am thinking is this… I would like a way to be able to turn off the the white led and just leave the blue ones on at night thru smartthings. Is there anyway that i could do this? Anyone have any ideas on how to set this up?
