There are two blue and green Rankin tartans which are custom weaves and thus likely expensive. As above best bet is to find your kilt maker and let them order precisely what they need to make you a kilt.

There is another red-black-blue-green-white Rankin tartan listed on Scotweb's tartan list as a standard weave from Dalgleish's Artisan Weaver collection:

http://www.scotweb.co.uk/tartan/Rank...rchterm=rankin

It lists there as either 16 or 12 oz tartan in double width with minimum order lengths of 4 and 1 meter respectively. Not too expensive at roughly $53US per meter double width for the 16oz. Dalgleish fabric is luxurious and very well made, as I have a couple pieces of their fabric waiting to be made into kilts whenever the finances come around. If this is the Rankin you are looking for this is a sweet deal. Don't forget to access Scotweb by clicking on their advert upper right corner of most XMTS pages which gets you the xmarks discount price, about 10% off their regular prices.

For a little over $200 you can have the fabric for a nice 8 yarder, for $100+ enough for a Newsome 4 yd box pleat. Or you can have Scotweb just make up an 8 yd Balmoral kilt for less than $340US. Not bad deals for a less than common tartan.
