Blue And White Christmas Lights: 11 Ideas For A Winter Wonderland

Blue and white Christmas lights turn a house into a winter scene, even in a year without snow. The pairing reads as frost, moonlight, and fresh ice, and it looks equally at home on a modern farmhouse, a brick colonial, or a row of evergreens at the edge of the yard. The trick is balance: too much blue goes dark and moody, too much white loses the color. These ideas show how to combine the two, layer by layer, from the roofline to the ground.

Start With Cool White, Not Warm White

The single biggest decision is which white to use. Blue pairs best with cool white (6400K), which has a crisp, icy tone that matches blue's temperature. Warm white has a golden glow that can look yellow next to blue. Every product in these ideas uses cool white for that reason. Keep that same white everywhere, too: one warm white string tucked into a cool white display is the quickest way to make the whole scheme look slightly off.

Next, decide on a ratio. A display that's mostly white with blue accents feels bright and elegant. An even split feels festive and graphic. Mostly blue with white highlights feels dramatic and nighttime-dark. Pick one and carry it through every layer.

1. Alternate Blue And White C9s On The Roofline

The roofline is the frame for everything else. Screw C9 Blue Faceted ProCore® LED bulbs and C9 Cool White Faceted ProCore® LED bulbs into a C9 stringer in an alternating pattern. The faceted lenses throw sharp points of light, and the alternating colors read clearly from the street. For a softer look, try two white bulbs for every blue.

2. Hang Cool White Icicles Beneath A Blue Roofline

For a frozen-edge look, run blue C9s along the roof and hang 70 M5 Cool White LED Icicle Lights beneath the gutters. The white wire disappears against white fascia, and the icicles drip light below the blue line like real ice. Each set covers 6.5' from the first drop to the last.

3. Wrap Tree Trunks In Blue, Canopies In White

Deciduous trees become sculptures when you split the colors. Wrap the trunk and lower limbs tightly in 100 5mm Blue LED Christmas Lights, then wrap the upper branches in 70 5mm Cool White LED Christmas Lights. The blue base glows like shadowed ice and the white canopy catches the eye from a distance. Each 70-light string has 23' of lit length, and up to 45 connect end to end.

4. Light An Evergreen In The Arctic Palette

For a single string that does the color mixing for you, the 50 5mm ColorCraft® Arctic LED Christmas Lights blend teal, blue, and cool white on one string. Wrapped through a spruce or a pair of entry topiaries, Arctic reads as blue and white from the street with a hint of teal up close, a palette you won't find at the big-box store. Each string has 24.5' of lit length on 6" spacing.

5. Add Sparkle With Cool White Strobes

Real frost glitters, and strobes are how you get that effect. Layer 50 5mm Cool White SuperSpark® LED Strobe Lights over steady blue lights on a tree or hedge. Every SuperSpark® bulb fires rapidly and randomly, like a tiny camera flash, so the steady blue looks like it's covered in glittering ice.

6. Use A Two-In-One Blue And White Strobe String

If you'd rather run one string instead of two, the 50 5mm Blue and Cool White Dazzle LED Strobe Lights do both jobs. Every fourth bulb strobes cool white while the rest glow steady blue. They're a great fit for railings, porch columns, and smaller trees where layering two strings would get bulky.

7. Blanket Shrubs In Blue And White Net Lights

Net lights are the fastest way to cover a shrub evenly. The 4' x 6' Blue and Cool White LED Net Lights mix both colors across 100 lights, so a row of boxwoods reads as one even, frosty layer. Each net has a 24" lead to reach the next shrub, and up to 18 connect end to end.

8. Make The Shrubs Breathe With Slow Fade Nets

For gentle motion at ground level, the 4' x 6' Arctic DreamSpark® Smooth Fade Net Lights slowly fade blue, cool white, and teal in and out, like light moving across ice. Pair them with steady nets on neighboring shrubs so the motion stands out.

9. Outline The Walkway In Alternating Blue And White

Carry the roofline pattern down to the ground. Use a C9 stringer along the walk, push each socket into a 5" Lawn Speed Stake, and alternate blue and cool white C9 bulbs to match the roof. Our pathway lighting guide covers spacing and ordering math.

10. Frame Windows And The Front Door In Cool White C7s

Windows and doors are where visitors see the lights up close, so give them a crisp white outline. Smaller C7 Cool White Faceted ProCore® LED bulbs on a C7 stringer trace a window frame neatly without overwhelming it, and the white outline makes every blue element around it look deeper. For a front door, run the C7 line up one side, across the top, and down the other, then hang a wreath wrapped in blue mini lights in the center. If your house has a row of matching windows, outline every one of them the same way: repetition is what makes a facade look designed rather than decorated.

11. Hang Snowflakes Where The Eye Lands

Lighted snowflakes are a natural fit for a blue and white scheme. Hang one in a front gable, over the garage, or on a large tree limb, and let it act as the focal point that ties the palette together. Browse our snowflake lights, and see our snowflake motif display guide for placement ideas.

Three Blue And White Plans To Adapt

Mostly White, Blue Accents

Cool white C9s on the roofline, cool white icicles, and white-wrapped trees, with blue reserved for one feature: a wrapped trunk, the front door frame, or blue and white nets on the entry shrubs. Elegant and very bright.

The Even Split

Alternating blue and white C9s on the roof and walkway, blue trunks with white canopies, and blue and white nets on every shrub. Festive and graphic, and easy to read from the street.

Winter Night

Blue C9s on the roof, blue nets, and blue-wrapped trees, with cool white SuperSpark® strobes layered over the evergreens for glitter. Moody and dramatic, especially on a dark-colored house.

Power And Timing

LED strings sip power. A 70-light 5mm string uses 4.8 watts, a 4' x 6' net uses 12 watts, and each ProCore® C9 bulb uses 0.84 watts, so even a large blue and white display fits comfortably on a few household circuits. Our wattage and circuit guide walks through the math. Plug everything into a 2 Outlet 15 Amp Outdoor Photocell Timer to turn the lights on at dusk and off after 2, 4, 6, or 8 hours.

Plan Your Blue And White Display

Choose cool white, pick a ratio, then work from the roofline to the ground: C9s on the roof, icicles under the eaves, wrapped trees, net-lit shrubs, and a staked walkway.
