Heavy Plot Cerulean

Old English hefig, weighty — cognate with heave. Used as a color modifier since at least the seventeenth century to indicate weight in saturation as much as value: heavy with pigment, heavy-bodied. In the engine's adjective grid, heavy sits alongside deep and plush in the dark-and-saturated quadrant. Closer to a fabric description than a pure value word.

Old English plot, small-piece-of-ground. As a color modifier, plot implies a tilled-garden-bed quality, the visual register of English-cottage-garden-and-allotment hand-tilled-and-cultivated small market-garden vegetable-bed surfaces under English-cottage-garden-and-allotment summer-tilling light. Sits at the modifier-and-place end of the grid, parallel to yard and garden in usage.

From the Latin caeruleum, originally referring to dark blue paint pigment of the Roman world, then via French céruléen into English. As a modern art-supply name, cerulean blue is the cobalt-tin oxide pigment introduced in 1805. The color refers to a clean, slightly green-shifted blue with the matte finish of mineral pigment in linseed oil: lighter than cobalt, deeper than aqua, with the painter's weight of a word for sky.
