Effetre's new Dark Zucca is a dark orange that gets, like most of Effetre's yellow/orange/red palette, gets darker when worked.
The colour itself is juicy orange with dark orange overtones, quite a bit darker than the unworked rod.
If you love orange - you will swoon over this. As with other Effetre oranges, I suggest stocking up, as their "hot" palette of colours has significant variability from batch to batch, and there is much wandering the aisle of glass shoppes, with tiny stubbs of rod ends, wailing and gnashing of teeth - "It's different now ... I loved that colour ... ."
