If you've been anywhere near Pinterest in the last 12 months then we're guessing that there'sbe no doubt in your mindthat rose gold is officially the colour of 2015. From beauty products to the iPhoneto bags, it's a shade that's been all over the catwalks this year and if this sneaky little hint is anything to go by, it looks likeKylie Jenner is keeping thatin mind while developing her snazzy newLip Kit collection.

The first batch of products sold out in 30 seconds flat,but with more set to hit the internet in the next couple of weeks, there's speculation that the youngest member of the Keeping Up With The Kardashians gang might just have dropped a hintabout abrand new shade:rose gold.

So far we've seen three huesin the range, which range from the chocolatey True Brown K to the soft, dusky pink of Candy K and the mid-tone Dolce K. But it sounds like Kylie might be moving away from the matte tones for the next shade after a pic was posted to the Lip Kit's official Instagram showing a molten metallic golden tonethat doesn't match anything we've seen so far.

Interestingly, the snap has since been taken down,but thathasn't stoppedbeauty lovers speculatingthat this could be an advance preview of what mightbecome the next product featured in the line.

While it was captioned '#inspo', it's the only snap on the page so far that doesn't feature something directly related toKylie's kits, so could be a big old hint about what she's planning to donext.

That said, the pic itself definitely isn't a new Lip Kit colour and it turns out that the photoof the dramatic, oozing rose gold tone actually comes from makeup artist Vlada Haggerty's work and was made using a mixture of Graftobian Makeup's metallic powder with a clear lipgloss. Taking to Instagram to dispell rumours it's a Kylie Jenner Lip Kit product, she set the record straight and crushed a fair few of our dreams in the process.

All that aside, a shade like this would definitely be unlike any lipstick -liquid or otherwise -thatwe've seen before, so fingers, toes and eyeballs crossed Kylie's got something like this up her designer sleeves.
