King Cole Firefly Aran — Firebug (6570)

Firebug smoulders. Deep crimson and blackcurrant wine shift into charcoal and near-black, with warm coppery-bronze passages glowing through like embers catching light. It's the most dramatic shade in the Firefly range and easily the most flattering against warm skin tones.

The colour changes are gradual rather than stripy, so a plain stockinette body builds soft bands of red and dark that look considerably more complex than the effort involved. Worked in lace or a scallop edging, the shimmer picks out every eyelet.

Firefly Aran isn't a glitter yarn — there's no metallic thread and no scratch. The shimmer is built into the fibre itself, giving knitted and crocheted fabric a soft halo and a light-catching glow that shifts as you move. Buy your full quantity in one go where you can, and join new balls at a matching point in the colour run to keep the transitions seamless.
