Just a drive-by note on this from a few days back - I think the problem with the Huddersfield site is they've taken a few of the pictures from very close up with a flash, completely washing out the colors. I haven't seen any of the books, but I *think* for instance in the Fresco II collection - https://shop.hfwltd.com/collection/23 - the following are actually the same base color: 0531, 0552, 0557, 0559, 0562, 0564 0520, 0554, 0560 etc. Basically I think the "Colour" properties are correct, and any two swatches with the same "Colour" text are the same base colour, but the pictures are way off. I think the darker pictures are much closer to the actual colours. I'm sure some of the legends in this thread would have the actual sample books and could confirm, but it sure makes it difficult to order off the website with any reliability. The Alsport collection doesn't look as badly affected, but that one "blue" swatch sure does look like the same kind of washed-out photo.
