How to Warm Up a Gray Room Using Lighting

Lighting & bulb tips to make your home look inviting…

When trying to update and warm up a gray room, lighting is often the last place we look, when it should be the first. This is even more the case if you don’t want to repaint or replace any of your gray finishes.

Why is lighting so important for a gray-inspired room?

While the color of your gray finishes won’t change, they are what they are – how you SEE them could. So, if you want more warmth, let’s add some!

When designing the ‘millennial gray home,’ many builders and homeowners opted for cleaner, daylight bulbs. While MY ideal daylight is warm, as it relates to bulbs, ‘daylight bulbs’ can be a pretty cold look.

Seriously, I can’t even tell you how many times I’ve said to my Online Color Consulting clients, ‘I think you should change your light bulbs, ‘ and more often than not, they need to be warmer.

1. LET ME INTRODUCE YOU TO KELVIN, HE’S A GREAT GUY

While Kelvin might sound like a friendly neighbor’s name, this Kelvin is about to make your home a whole lot more inviting-looking.

Your light bulb’s Kelvin rating should complement your paint color and the ideal mood of your room.

For example, the gray walls of this next north-facing room demand a warmer, softer, lower Kelvin light bulb…

A higher Kelvin/cooler bulb would compound the cool temperature of the north-facing light, the gray paint color on the walls, and the gray-inspired quartz countertop.

While some paint colors are shown at their best in a cooler light (higher Kelvins), in general, paint colors are more livable and welcoming in a softer, warmer light (lower Kelvins). 

Unscrew those bad boys and see what you’ve got.

1. If your bulbs have a Kelvin rating higher than 3500, you’re compounding the cool effect of your gray room. Heck, even 3500 isn’t great.
2. Buy two types of bulbs – one @ 2700K and one @ 3000K. Try both (one temperature at a time) and see what feels and looks best.
3. Replace more than one bulb when sampling temperatures (if possible). If your room only HAS one fixture, cool beans, but if you can change 2+ bulbs in this experiment, give ‘er a go.

While it’s less of a concern (many of today’s bulbs are of reasonable quality), you might also check the CRI of your light bulbs to ensure they’re not casting a green-hued light on your beautiful paint color. Cheaper bulbs often have lower CRIs.

2. CREATE A TRIANGLE OF LIGHT

You can create this decorative triangle using two table lamps and a floor lamp or three table lamps.

When you draw a line between the three light fixtures (not literally), it should create a triangle.

This way, most of your room has light, and there’s a connection between the sources. If you want to add more, fill yer lil’ boots.

3. USE THE RIGHT AMOUNT OF LIGHT FOR YOUR ROOM

You need to determine the wattage your room requires, especially if it has limited natural lighting. A well-lit room can support a variety of colors and depths, regardless of whether the light is natural or artificial.
