I definitely feel your boost on the tail-end of your post. My eyes are kind of buzzing from reading it, even as I am writing this. Good going!
As for the colors to use, I probably wouldn't use blue unless you are boosting with orgonite, as positive orgone energy is blue. Otherwise, you are pulling on every other blue energy within your reach

MY suggestions would be green and pink, and that is normally what I use in my double helix now.
Oh, I came up with another great boosting method! I now imagine standing in about 4 feet of water, with a raging green ocean behind me. As I am boosting, the water recedes from me and creates a giant tidal wave. The wave crashes down, but I kind of imagine it crashing all into the back of my heart and then out into the double helix and to the target. Cool, huh?
Glad you like it, and it's awesome that you can book pretty easily. Also, try taking a crystal wand (either a natural point or cut) and put it up to your heart and boost through it, especially if it is green or pink (green adventurine, tourmaline, malachite, rose quartz, rodochrosite.. heck, quartz works well. I use a Lemurian Seed). I combined all of these techniques when I boosted my Lemurian Seed post.
Love and light,
