Quick answer

If you want a soft, everyday color change with a hint of mystery, choose Treble Maker. If you prefer a bold, dramatic shift with a holographic sparkle, Witching Hour is your match.

Color shift: from subtle to striking

The biggest difference between these two thermals is how they transition. Treble Maker goes from a deep black when cold to an amethyst purple when warm, with dusky purple shades in between. That means you get a full spectrum of purples, which feels playful yet wearable.

Witching Hour, on the other hand, shifts from black when cold to spiderweb grey when warm. It’s a more monochromatic change, but the scattered holographic effect adds shimmer and depth that keeps it from feeling flat. The grey is lighter than black, so the contrast is obvious but not as colorful as Treble Maker's purple.

Finish and texture: holographic vs. classic

Witching Hour has a scattered holographic effect, which means it catches light with tiny sparkles. This makes it a great pick if you like a little extra glitz on your nails, even when the color is dark.

Treble Maker is a classic thermal without added sparkle. Its charm is in the color transition itself, so if you prefer a clean, understated look, this one lets the shift do all the talking.

Trade-offs to consider

  • Color range: Treble Maker offers a wider spectrum (black to amethyst purple), while Witching Hour stays within a grey-to-black range. Choose Treble Maker if you want more color variety.
  • Finish: Witching Hour has a scattered holographic effect; Treble Maker does not. Pick Witching Hour if you want extra sparkle and dimension. If you're torn, ask yourself: do you want a colorful shift or a shimmering one?
  • Occasion: Treble Maker's purple tones feel more playful and versatile for day-to-day wear. Witching Hour's grey-and-black palette suits gothic or evening looks.
