So I'm knitting this hat here:

and I've run into a problem. The pattern has you knit 7 rows of each color and you increase at the beginning of every other row (1, 3, 5) and decrease at the beginning of every other row (2, 4, 6) so it comes out to be a sort of parallelogram. You bind off and then pick up 3 stitches in each stripe along one of the long ends (42 sts total) and then the next 2 rows are decrease rows for head shaping. The only problem I have is that the pattern doesn't tell you which color to use to pick up these 42 sts and knit these 2 decrease rows. I started the parallelogram with white and ended it with blue. I'm going to do the cuff in white but these 42 sts are totally seperate from that. Help? Please? Here's the pattern:
Materials:
Use No. 8 knitting needles
Any worsted weight yarn (2 coordinating colors). 2 oz. of each color will make a cap.
Cast on 30 stitches. Knit 6 rows, increasing one stitch at the beginning of every odd row and decreasing one stitch at the beginning of every even row. (Inc. rows 1, 3, 5 and Dec. rows 2, 4, 6).
Row 7: Change yarn and knit rows 1, 3, 5; purl rows 2, 4, 6 doing increases on knit rows and decreases on purl rows.
Continue pattern until 7 stripes of each color are done. Cast off.
On one long edge, pick up and knit 3 stitches in each stripe (42 stitches).
Row 1: Knit 1, Knit 2 tog. across row.
Row 2: Knit 2 tog. across row. Cut yarn and thread thru needle. Pull yarn thru remaining stitches and fasten off.
Cuff: On other long edge, pick up and knit 6 stitches in each stripe (84 stitches). Knit 1, Purl 1 for 2-3 inches. Bind off.
Sew side seam and make pompom for top and attach to hat.
** The size of this cap changes according to needle size and yarn.
What color would you use?
