Coralis is a neon pastel-ish colourway that is a hot pink, but with neon peach undertones (so more on the warm side of pinks than on the cool punk shocking pink). Pair it with anything - brights, neutrals especially, blues...it even looks good with brown!
I'm going to list variations of this colour here also - Hot Coralis is just a more intense, fluorescent version of the same colour - a few shades deeper for intensity. Coralis is the regular shade; Hot Coralis is the intense, deeper and more eye-popping shade of this colour.
