NO more yellow. Yellow is a color that you need 1/4 of what you think you need to get the effect. It can truly take over the quilt and I know what your feeling because I learned a hard lesson with it myself That Said.. its a pretty quilt kind of colored like a pansy and everyone loves pansies so you should finish it with what you have and find comfort in the fact you can now start something NEW.. it helps to lay out the colors you bought in a swamp pile on the bed or floor. If you think one color is used more than the others leave a much bigger piece of that unfolded and then fold the others to the approx preportions they would be used. Stand back, squint with your eyes and look at what you have.. does it blend? does something yell at you when you look at it? does something that worked when you picked it not work at all when you view it this way in regards to the other items sitting with it? There is probably a good word for this, I however dont know it. I know there is a fancy mini reverse magnifier that you can use to view through that does a similar thing.. I like to squint. Excellent at it. And I can afford the tools required. Be easy on yourself and the quilt.
