Sherwin Williams Mercurial SW 9550: LRV, Undertones and a Little More

When it comes to finding the BEST paint colour it’s ALLLLL in the undertones. Okay, so maybe it’s a bit more complicated than that, but that’s why you’re here, learning all about paint colours so you can choose the best one for you and your home!

And today we’re learning about…

In order to show you RELATEABLE & REAL homes, I ONLY use photos from my Online Colour Consulting clients. This means I don’t always have the quality pics I need, but DEFINITELY have some SUPER helpful info to help you on your way!

What type of paint colour is Mercurial? Is it warm or cool?

Mercurial is a gray paint colour with a soft subtle warmth to it. And when I say subtle, I ain’t kiddin‘. If you have north-facing light, expect to see Mercurial lean EASILY back into its gray, looking slightly cool. However, if you have south-facing or afternoon western sunshine, it will lean that bit warmer, without going full taupe.

PLEASE NOTE: Sherwin William Mercurial is in the DESIGNER EDITION and can only be made in Sherwin Williams Emerald paint, no other lines.

What is its LRV?

Mercurial has an LRV of 61 which is a fantastic depth for the average room. This LRV puts Mercurial in the ‘light’ range (learn more HERE).

Not sure what LRV is? It could save your paint lovin’ life – read all about it HERE.

What are the undertones of Mercurial? Is it a TRUE gray?

While Mercurial doesn’t have overwhelming undertones, it’s FAR from being a true gray. Like every gray paint colour, Mercurial has an undertone – a VERY subtle, warm violet one.

What’s the best way to sample a paint colour, should I just slap it on the walls?

Like with every paint colour, I highly recommend using SAMPLIZE. Samplize is a peel & stick paint sample that you can easily move around your room for over HALF THE COST of traditional sample pots – and they deliver right to your front door!

HOWEVER, Samplize doesn’t have this new line of colours yet. In the meantime, you can EASILY do a ‘custom paint order’ from Hello Paint, which is a Canadian company (they can ship to the US)! Type in the name of the colour you want, and if it doesn’t come up, go near the bottom of the page and you’ll see the ‘Create a Custom Colour’ area – works like a charm!

Here’s a link to the SAMPLIZE site if you’re curious!


What’s the best white paint colour for my trim?

If you’re painting your walls Mercurial, look for a white paint colour that’s soft and slightly warmer OR clean and true. I wouldn’t look at cool, icy whites or overly warm ones.

Is this a good colour for the exterior of my home? 

Mercurial has the potential to be a good exterior colour as its undertones should humour many of the popular stone and brick coverings. Expect it to look that bit warmer in southern sunshine and to wash-out considerably if it gets a good hit of natural light.

Does Benjamin Moore have a colour that’s the same as this or similar to it?

GOOD QUESTION! Every colour has its own particular nuances and there will be NO perfect match – you WILL see shifts in undertones, temperature and depths, but you could check out…

  • Benjamin Moore Nimbus – a bit darker, but with similar intentions
  • Benjamin Moore Collingwood – a bit warmer

Check out Benjamin Moore Collingwood in the next photo, which will give you a good ‘general idea’ of what to expect with Mercurial…

BTW, if you’re thinking of colour matching between brands, I suggest you read THIS first.

What type of paint colours will look good with Mercurial?

While Mercurial will be VERY FUSSY about being partnered with warm colours like beige, tan and cream, it likes a whole RANGE of cool colours. Here are a few to get you started…

  • Gray-blues could be a stunning complement, ie: Sherwin Williams Network Gray
  • Gray-greens could also work well, ie: Sherwin Williams Cityscape
  • Slightly darker grays with similar OR different undertones, ie: Sherwin Williams Tinsmith
