Oh no Valencia....the SAs have a great way of confusing us all!! I bet it will be a similar color to raisin. Raisin was so popular when it first came out..and still is!! I would assume it would be similar...perhaps a little more purplish. I have not seen or heard about it.
I've seen the swatches of Prune in Boxcalf and Swift, and it's absolutely gorgeous!!!! It's a dark red with a hint of purple and a hint of brown: like dark red wine!!!! Nothing to do with Raisin, which is purple!!
I have a prune Kelly and the color is very different from raisin. I agree with duna and frenchiefan on the color description. My prune is chevre mysore and it's like a very, very dark red wine with brown tones.
Here are pics when I was still "La Vanguardia" lol!
In Boxcalf it's definately more red than either brown or purple: it's a very warm burgandy colour, that reminds me of dark red velvet (it's a childhood memory, I don't even know if it exists anymore!) but, even though I'm particularly partial towards Box, I can guarantee that, if you like H reds, you can't NOT love this colour!!!!! I'm going to order something in it ASAP!!!!!!!
