Lg k8 change orange to blue? / any tips for pure droud to lg gui?

[Android Central Question]

Hi
Moved from a nexus 4 to lg k8 and this orange is driving me nuts. I love the black based theme offered but cant deal with the orange. Any way i can change this please? Preferably to blue?

Also any tips for moving from pure droid to the lg ui?

A few questions are bugging me and im hoping its due to a ui change and missing a setting so any help with these would be great.

The break circle to unlock the phone and then enter your patton is proving tiresome. Is there a setting somewhere?

Any way you can get the 6 dot app button on the home screen?

Any way to show the alarm time on the lock screen?

Thanks
