Could these be used as spot lights for a small event with a stage?

Yes， you can. This light have 120 RGB colors+ Warm white light, and the brightness can be adjusted. It can meet your multiple uses.

Do these lights make a true blue color dark blue not purple-ish

YES, these lights can make a true blue color. In order for this to happen, once you tap the blue button on the remote, tap it another three times and it will make your lights a true blue color. With one tap only on the blue tab it won’t change it to a true blue. But if you continue to tap the tab it will continue to darken to a true blue color. These lights work GREAT! I have six of them due to them being the best lights I’ve been able to find on Amazon!
