But if you add a green with a white background it's going to come in conflict with the red and they will fight for dominance. So if those are your color choices placement is going to become incredible important.

Thanks for your effort, energy and knowledge. Color will be so much easier from now on.
The lesson here is constantly pay attention to the value of your colors/fabrics.

Triad - I think we have all seen primary color quilts done for children they are bright and charming and eye catching. But triads can also be busy and fight with one another. There will always be two colors on the same "side" of the color wheel. So you will either have two warm colors (dominate) or two cool colors (submissive). A neutral will "control" this color combination and help make it into the color scheme that will pop. If you have two warm colors and choose White that will become the dominate color and will calm down the yellows and reds. If you have two cool colors and choose black or brown then your warm color will really dominate while the blue and green will blend with the neutral.

Tetrad - This one is fun lets say you choose yellow and purple as your complementary colors. You won't use either of those colors. Your color palette will consist of orange and green, blue and red. Here the orange and red will dominate and the green and blue will be submissive in the color scheme. Varing the value of the colors in your fabric choice will enhance the wow factor but placement of the different colors requires very close attention.

Analogic - This is one of my favorites. I think it can make some very elegant quilts. With three colors next to each other you can have Yellow, Orange, Red combinations where all the colors are dominate with yellow being the "lightest" value and thus taking the main stage. With red being the darkest and thus falling to the background color. A large focus pint with these colors can make some fantastic medalion quilts. The addition of neutrals can definitely add drama and impact.

Accented analogic - 4 colors with a complementary color as a part of the mix can make for just about any combination you would like. Add neutrals and the sky is the limit. Just watch out that it doesn't become chaotic.

I'll try and look up any questions that you have and get you answers. I hope this has helped.
