New old stock from my shop Pins & Needles in Devizes, I've had to take it off the shelves to make room for new season yarns.
Rigadritto is 54% wool, 46% acrylic, their suggested tension is for that of a chunky yarn (6mm needles) but as it's brushed it can be versatile - I've used it as an Aran and you could possibly use bigger needles and make a fabric that's more lacy and drapey. Each 100g ball has approximately 270m so it goes a good way.
The colour changes have background colour (black, white, neutrals) that appears in stripes throughout. It gives a very multi-coloured effect if worked in rounds/squares rather than stripes.
I do have some of the patterns available - please ask if you'd like one and I'll sort it out for you. They are £3 each when bought at the same time as the yarn.
This product is no longer in the shop in Devizes but you may arrange to pick up from there to save on postage.
