changing colors with showing 1st row of stitches

[aineepooh1]

I am wondering how i can fix my problem.
I am knitting an afgan co 60 stitches sz 17 needls. i started with brown then changed to black. the stitches that have both black/brown are on one side, the other side it looks seamless(you can't see the row of stitches from the color change) NOW i want to add a third color but when I knit stitch I see the stitches from new color on the oposite side from the one with the black/brown stitches. How do I get the color changes on all one side (WS) i guess. I tried knitting first with the 3 rd color and the stitches showed so then I purled and the same thing happened.
What am I doing WRONG???
thanks

Do one more row and then change colors and you should be good.

You have to change colors on the same side as you did the first time. Two colors always show on a purl side, so you have to knit into a knit row.
