If there's a stripe running down a pleat (or in a change of color... from green to brown or brown to white), it should be in the CENTER of the pleat, not off to the side. Keep in mind that when you pleat to the sett, it doesn't have to be EXACTLY to the thread the same... you can make it look like the sett, but increase or decrease certain fields to make the pleats look better.

I've divied it up here how I'd probably do it (mine are the black lines). I might do 2 'all white' pleats instead of 1, but you get the idea. Some of the lines are ABOVE the others to show where I'd increase a field of color to stretch it. The finished pleats should all be the same width (my poor photoshopping ability may not be):
