Also, due to the balanced tone, SW Endless Sea will hardly make your home feel cold or chilly. Instead, it will radiate a feeling of pleasant freshness and coolness around.

What LRV SW Endless Sea Paint Color Has and How It Reacts to Light?

When you are choosing paint colors for your home, LRV is one of the most essential things to take into consideration. LRV (light reflectance value) shows how much light colors can reflect from the wall, as well as how much light they can absorb. The LRV scale ranges from zero (black) to 100 (white).

The LRV value of SW Endless Sea is 9, which places this color on the darker side of the light reflectivity scale. However, thanks to its balanced tone, this blue doesn’t typically read obscure or moody. Nevertheless, consider that it will add plenty of depth to the space!

What Is the Best Trim Color to Use With SW 9150 Endless Sea?

If you are searching for the best trim color to use with SW Endless Sea, stick with white, and you won’t make a mistake! This blue works exceptionally well with white trim, moldings, and window frames. White accents will make this blue reveal its true hue much better, making the color read somewhat brighter.

However, it’s essential to choose the correct shade of white! For example, warm and creamy whites (like SW Shell White) will not work well with SW Endless Sea because of the “dirty” look they create.

Instead, you’d better opt for cooler and crisper whites. For example, you might want to consider the following colors:

SW 9541 White Snow (for a crisper look)
SW 7006 Extra White (for a softer contrast)

Where to Use SW Endless Sea Paint Color In Your Home?

One of the biggest stumbling stones for many homeowners is finding the room that will host the selected paint color best of all. Not all paint colors are so versatile that you can use them in any room successfully. Often, you have to consider the way the room is lit, other colors used in it, and even the texture of fabrics and furniture!

With such a complex hue as SW Endless Sea, finding the best palace for using it may become a challenge! Below, you can find a description of how this color will work in different rooms of your home.

This guide will help you understand better where this blue will be a win-win color choice and where you should avoid using it.

Endless Sea SW 9150 in the Living Room

This blue hue can add a bold and pronounced statement to your living room, but you must ensure the space has ample natural light. Otherwise, SW Endless Sea will read darker than it is, making the room feel enclosed and moody. Pair it with cooler and crisper whites on ceilings and trim, and use white curtains and/or carpet to make the space feel brighter and airier.

Endless Sea SW 9150 on the Bedroom

In bedrooms, this deep hue works best as an accent wall color. Paired with white accents on the trim, as well as with the white walls, this blue will make your bedroom feel cozier yet not too dark. For more color in the space, consider using light greiges on upholstery and/or bedding, and add mustard yellow accents through pillows.

Endless Sea SW 9150 and Kitchen

SW Endless Sea works best on kitchen cabinets and islands since it’s too dark to be used on the walls. Instead, leave the walls crisper white to make the space feel larger and brighter. SW Endless Sea pairs nicely with tiles and brass/golden fixtures, so it will fit most kitchen interior styles.

Endless Sea SW 9150 on the Bathroom

Since bathrooms typically have little light, we recommend you use SW Endless Sea very carefully there. The best way to incorporate this hue would be to use it on the vanity or paint one of the walls if the size of your bathrooms allows that.

Endless Sea SW 9150 for the Exterior Use

Despite being rather dark, SW Endless Sea can work on exterior walls. As an option, this blue can be used on your front door if the walls are painted in another, brighter color (e.g., white).

Now you can see that even deep and saturated blues like SW Endless Sea can find their place in your home if you know how to use them.

Now you know how to make this blue work in different rooms and what to expect from this color in distinct lighting conditions. Also, you learned how to coordinate it and what colors to use with it to make your home feel more welcoming and cozy.
