Solid Caladium

#a03d45
Notes

Solid Caladium (#A03D45) is a true red with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (355°, 45%, 43%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. For a confident two-color system, pair it with its complementary cyan. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Solid
adjective

Latin solidus, firm, dense — used as a color modifier since the seventeenth century for hues that read as continuous and unbroken: a solid blue is one with no variation across the surface. Implies high saturation combined with optical density. Sits in the bold-bucket alongside strong and robust, slightly more focused on uniformity.

Caladium
noun

The genus Caladium — tropical understory plants whose heart-shaped leaves are colored red, pink, and white through the centers and along the veins. The color refers to a Caladium bicolor leaf: a saturated, slightly cool deep red with the satin finish of tropical leaf surface. Cooler than coral, warmer than burgundy.
