Here's a list of the colours I used starting from the top: P219 8, P211 148 P803 56, P216 19, P621 105. The second number is the dyelot. Remember that every dyelot of koigu is unique so it might be hard to reproduce. I bought all the yarn from Four Seasons Knitting about a year ago, but she may have more. J0-Ann, the owner, picked the colours for me and she's amazing. I'm sure she can suggest some amazing colours for you too.
And, some more photos, might as well take advantage of the sun.
