Crisp Scarlet & Baby Blue is a vivid complementary color palette tagged neon, black, red. Scarlet and Frost sit nearly opposite on the color wheel, so the pairing has real energy; keep one as the accent. These are bold, punchy colors that need generous white space around them. Warm and cool hues are mixed, which adds depth.
