Lands, long before all our fancy technical tools were even invented, I was 'seeing' quilts in terms of pattern rather than color. What I couldn't quickly see, I drew out on graph paper and colored in whatever way came to me. I still do this, but, now I often graph in the Paint program on my laptop.
I believe if you will train yourself to "find the block" it will be easier for you to see the quilt as pattern, beyond the color.
