Project calculator
Overview
F&B Hague Blue is a dark blue with a blue (cool) undertone and a calculated LRV of 7.1. Against white trim the contrast ratio is 7.79:1, which gives strong, graphic contrast; painted tone-on-tone, the herringbone pattern shows only through its shadow lines.
Herringbone 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 76.93 m of 2.5 cm molding, or 33 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 herringbone pattern
Chevrons are pairs of short pieces meeting at a point down the center of each panel. Keep the angle and the vertical spacing identical so the rows line up across frames.
Painting molding in F&B Hague Blue
Blues work best fully drenched: wall, molding and chair rail in one color, with a slightly higher sheen on the trim.

Questions
How much molding do I need for a 15 ft living room wall with herringbone frames?
About 76.93 m (252 linear ft) including a chair rail and 10% waste, which is 33 sticks of 240 cm. That assumes 6 frames per row, 25.3 in wide, on an 8 ft ceiling.
Is F&B Hague Blue warm or cool?
F&B Hague Blue has a blue (cool) undertone and reads as a dark blue. Its calculated LRV is 7.1, so it absorbs light, so tone-on-tone molding reads as deep relief.
Should trim be the same color as F&B Hague Blue 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 (7.79:1), and black trim gives 1.9:1.
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.
