Project calculator
Overview
Navy Blue is a very dark purple with a violet undertone and a calculated LRV of 3.5. Against white trim the contrast ratio is 11.18:1, 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 on the lower third of the wall under a chair rail; the upper wall stays plain. On a 15 ft wall with an 8 ft ceiling this gives 6 frames per row, each 25.3 in wide, 21 in tall. The layout uses about 20.56 m of 2.5 cm molding, or 9 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.

Muted violets work tone-on-tone in bedrooms; keep the sheen low on the wall.

How much molding do I need for a 15 ft living room wall with picture frame frames?
About 20.56 m (67 linear ft) including a chair rail and 10% waste, which is 9 sticks of 240 cm. That assumes 6 frames per row, 25.3 in wide, on an 8 ft ceiling.
Is Navy Blue warm or cool?
Navy Blue has a violet undertone and reads as a very dark purple. Its calculated LRV is 3.5, so it absorbs light, so tone-on-tone molding reads as deep relief.
Should trim be the same color as Navy 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 (11.18:1), and black trim gives 1.33:1.
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.
