This is turning out wonderful. I don't thinks there is any real problems.
Take a look at the second block down in the first column, The lighter shades are one the outsides of the strips and there are two other places like this. All the other strip blocks are darker on the outside and lighter on the inside. They aren't wrong or anything like that but depending on what shade the center fabric is going to be, they might wash out the pattern if the colors are too similar.
I really like the overall look of the quilt and would be personally very happy with this accomplishment. I love scrappy quilts and I think even being color challenged as you say, you have a good eye for scrappy quilting.
Congratulations.
peace
