If you’ve been around here for long, you know my love for pretty paint color transformations runs deep! There’s just something about the power of paint that I love so much.

While I’m a big fan of soft, neutral warm white walls, I love a good pop of color, too. Especially pretty shades of blue, and especially here at our lake cottage where we have embraced a coastal modern style for our lake house decor! Check out Benjamin More Silver Gray, too.

This beautiful slate blue paint color is no exception, so I knew I had to share all about it. Soon, I’ll bring you a DIY for this cute little dresser makeover, too – we used the Ikea Koppang dresser to give us the high-end look we were after. (More details and sources towards the end of this post!)

Paint is the easiest way to customize your home, and I hope these guides inspire you to take the leap with a fresh new color! Use the drop down Table of Contents menu to navigate this post with ease. Let’s get started!

BM Slate Blue LRV

What is LRV? Click through for a full guide – but this is an important system to understand when you’re choosing paint!

LRV stands for Light Reflectance Value. It’s the measure of light a color reflects or, in other words, how bright a color is. On a scale of 0-100, 0 is true black and 100 is pure white.

Slate blue has an LRV of 43, which is surprisingly deep, in my humble opinion. Be careful using this color in spaces that don’t get much natural light, as it could easily darken a room.
