Do I go blue!?

I defintely do not like 20k, my friend had it in his tank and it was just to blue for me. Its coming around time to change my bulbs and Im wondering
if I go 14k, will I get more color but less growth?
Will the slow in growth be significant?
Will there be a major photoaclimation?

Just a few questions Im wondering and debating before I go buy.
