Hmmm. Correspondences actually already exist. I don't want to shoot your ideas down or anything. Try pink for love, red is more of a lust. Yellow is knowledge, purple is psychic.
But what if you did colors like sea green, or combined? I haven't seen anything too specific like that. Just the basic yellow, blue green. Nothing combined.
That's why it's the rainbow! It works specifically with the colors within the rainbow. And it's more than correspondences. I'm just working with those first.
I am told that with magickal applications, spell work and with whatever you do and especially with colors, it is good to assign your own meanings to things, color, objects etc.
I think it is good too, to establish your own meanings using pre-established meanings as baselines or guides. At least in the beginning. Also, we change based on experiences. Maybe you will want to create a book, specifically a rainbow color meaning book as your Bo's, or as a section of your Bo's or grime ire. It may be helpful to also put into that book your comparisons and contrasts to what are accepted and alternative assigned meanings which are put forth by others; if you feel those things will be helpful to you.
You sound like you are very creative, which I am told is a wonderful quality to have when embarking on or continuing your magickal journey.
I am inclined now, to look at your profile, though me myself, have not yet developed mine.

Why thank you. I'll probably be posting a ton more info on it once I get these simple correspondences in. I want other people's opinions because I'm pretty much out of ideas by now.
Giving it time to develop will often help.
You can begin to elaborate on the ideas which you have put forth already.
Studying your own work no matter how little you think you've done in the area.
