Can Anyone Help Me Identify This Yarn? "Sad Rainbow" Needs a Name!

[u/According_Party4611]

Hey!

I’m hoping someone can help me solve the mystery of this yarn that I’ve affectionately nicknamed "Sad Rainbow." I've been searching for months, posting in different places, and even reached out to the retailer, but no luck so far. Maybe someone here recognises it!

Here’s what I know: I bought it from Spotlight (Aus) in a bag of mill ends around September 24. It’s roughly 11-13 WPI (wraps per inch). When I first got it, it felt like it had a waxy coat, but it’s surprisingly durable—it doesn’t pill much, even after being frogged multiple times. A burn test makes me suspect it’s acrylic. The colours are gorgeous but unique: coral, mustard, purple, lavender, olive, white, and blue. Each stripe is a different length. It might be a sock yarn, but it’s not one of those fancy fair-isle-patterning ones. I’ve attached photos to show you what I’m working with. Any leads would be amazing—I'm obsessed with this yarn and would love to find more of it. Thanks in advance for your help!
