Overview
F&B Stiffkey Blue is a dark purple with a violet undertone and a calculated LRV of 10.1. Against white trim the contrast ratio is 6.26:1, which gives clear contrast; painted tone-on-tone, the picture frame pattern shows only through its shadow lines.
Picture Frame layout on a 10 ft office wall
Molding over the full wall height, upper and lower rows divided by a chair rail. On a 10 ft wall with an 8 ft ceiling this gives 4 frames per row, each 25 in wide, with 50 in upper and 21 in lower frames. The layout uses about 30.4 m of 2.5 cm molding, or 13 sticks of 240 cm, including 10% waste. A molding wall behind the desk doubles as a video-call backdrop.
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.

How much molding do I need for a 10 ft office wall with picture frame frames?
About 30.4 m (100 linear ft) including a chair rail and 10% waste, which is 13 sticks of 240 cm. That assumes 4 frames per row, 25 in wide, on an 8 ft ceiling.
Is F&B Stiffkey Blue warm or cool?
F&B Stiffkey Blue has a violet undertone and reads as a dark purple. Its calculated LRV is 10.1, so it absorbs light, so tone-on-tone molding reads as deep relief.
Should trim be the same color as F&B Stiffkey Blue walls?
Painting the molding the same color gives a modern, tone-on-tone finish where only shadows show the pattern. White trim adds clear contrast (6.26:1), and black trim gives 2.37:1.
How high should the chair rail be in a office?
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. A molding wall behind the desk doubles as a video-call backdrop.
