Scale is exactly where a strong color gets difficult, and it is why most large planters are grey, black or white. Pigment mixed through plastic has the furthest to fade on a saturated color, and a large surface shows that fading more plainly than a small one. Matte Cobalt Blue here is an automotive-grade paint system sprayed onto a fiberglass shell, so the color is a coating specified for weather rather than a dye trying to survive it.
Use it deliberately. Blue has no natural partner in foliage, so a large blue planter reads as an object rather than as a background, and one of them in a courtyard does more than a row along a wall. It holds up particularly well against white render, pale stone and weathered timber, and it fights warm brick.
The largest sizes ship by freight truck and are delivered curbside. Read the size table on each product page, because a family often mixes ground and freight sizes.
