If you don't mind, can you tell me which brand/lights are doing your 'green'? I steered away from Hue because I read many a complaint about its green color which is the most important color to me. The green lights in your pics look great and I was curious who made them.
The exterior lights are Sylvania Lightify retrofit kits. Amazon had two packs for about $70 a while back.
The interior track lights are Mi-Light GU-10 4 watt LEDs. I went with the 4 watt bulbs because the 5 watt ones didn't fit in my track lights. The cool thing is that they have six chips - two RGB, two warm white, and two cool white. You don't have to pick warm or cool and I set them in between for better color rendering on my photos. I purchased them directly from the manufacturer and they ended up being $10 each, shipped.
The bad thing about the Mi-Lights is that they don't work with any other systems. Thankfully ha-bridge can address that but you have a bit of leg work to get it working. It also means that you have to have an always on computer to run the bridge (it can be something as small as a Raspberry Pi).
I first played with the Mi-Lights with their four lamp kit from Thorfire which I see is down to $30 now. Not bad for four lights and a remote to play with. The remote is a bit touchy because it has capacitance controls. Just picking it up you typically turn things on and off by accident. Still, not bad for 30 bucks.
Here's the GU-10 lamps from Christmas to see a bit more of the green...

That was right after I hung the photos and before I setup the lighting for them.

Yes, I can change my exterior lights based on the holiday.
I'm happy with the color saturation on both systems.
