Striped Baby Cardigan

I'm working on making a striped baby cardigan. The yarn is Knitpick's Shine Sport, held doubled, and I have river (a nice bright-ish blue, but not neon by any means), cherry (a BRIGHT red, ever-so-slightly-pink but overall just a bright red) and cabin, a four-ply with a strand each of river, cherry, a light blue and a goldenrod type color. Photos are here, if you are interested.

The way I want to stripe it is as follows:


The cardigan is going to be about 7" long from hem to underarm and then another ~4 inches from there. The striping pattern I was planning was 4" of blue, 1" of the variegated, 2" of the red (this brings it to the underarm), 1" of variegated and 3" of blue to finish it off. I have begun this, though, and I'm worried that it is just Too Much Red, and somewhat too much of the variegated all in one bit. However, I don't think I have enough blue yarn to do 5" of blue, 1/2" (or 3/4") of variegated, then 1.5 (or 1.25") of red, then 1/2" (or 3/4") of variegated, then 3.5" (or 3.25") of blue.

I'm therefore thinking about keeping the 4" blue bottom edge and 3" blue top edge, and alternating variegated-red-variegated-red-variegated for the middle section. I'm not sure this will help though.

Any thoughts? Any pictures of similarly-striped infant/toddler sweaters/cardis so I can get an idea of proportions? Any leftover skeins of river?
