Overview
SW Tricorn Black is a very dark black with a neutral undertone and a calculated LRV of 2.9. Against white trim the contrast ratio is 12.04:1, which gives strong, graphic contrast; painted tone-on-tone, the picture frame pattern shows only through its shadow lines.
Picture Frame layout on a 15 ft living room wall
Molding over the full wall height, upper and lower rows divided by a chair rail. On a 15 ft wall with an 8 ft ceiling this gives 6 frames per row, each 25.3 in wide, with 50 in upper and 21 in lower frames. The layout uses about 45.82 m of 2.5 cm molding, or 20 sticks of 240 cm, including 10% waste. Center the layout on the sofa or TV rather than the wall when furniture is off-center.
Building the picture frame pattern
Each frame is four pieces of 2.5 cm molding with 45 degree miters. Set the frames out from the center of the wall, keep every gap equal, and let the margins at the corners match the gaps.
Painting molding in SW Tricorn Black
Near-black walls turn molding into pure relief; use a satin or semi-gloss on the trim so the profile catches light.

How much molding do I need for a 15 ft living room wall with picture frame frames?
About 45.82 m (150 linear ft) including a chair rail and 10% waste, which is 20 sticks of 240 cm. That assumes 6 frames per row, 25.3 in wide, on an 8 ft ceiling.
Is SW Tricorn Black warm or cool?
SW Tricorn Black has a neutral undertone and reads as a very dark black. Its calculated LRV is 2.9, so it absorbs light, so tone-on-tone molding reads as deep relief.
Should trim be the same color as SW Tricorn Black walls?
Painting the molding the same color gives a modern, tone-on-tone finish where only shadows show the pattern. White trim adds strong, graphic contrast (12.04:1), and black trim gives 1.23:1.
How high should the chair rail be in a living room?
About one third of the ceiling height: 32 in on an 8 ft ceiling, 36 in on 9 ft and 40 in on 10 ft. Center the layout on the sofa or TV rather than the wall when furniture is off-center.
