Stability and reliability carry the palette from Shadow Colonnade outward, with the remaining swatches arranged around that rather than competing with it. Shadow Colonnade to Pentelic White spans 79 points of lightness, so the palette can carry its own hierarchy without reaching for a second one. Aged Stone and Column Stone are close enough in hue and lightness that most people will read them as one colour, which makes them a pair to separate rather than two choices to spend.
Shadow Colonnade a near-black espresso brown, weight and gravity without going fully neutral.
Aged Stone a dusty taupe-brown, quiet and unassuming.
Weathered Marble a burnt or terracotta orange, warmth read through a rustic, sun-worn filter.
Pentelic White a peach or apricot tint, all the friendliness of orange with none of the volume.
Column Stone a dusty taupe-brown, quiet and unassuming.
The grammar of the Western built world - column orders, tripartite elevation, and the Parthenon's optical corrections have been the foundation of architectural education from Vitruvius through the Beaux-Arts.
