Three ways to name a colour

CSS accepts colour in a few formats: • Named: red, black, rebeccapurple. Fine for prototyping, limited palette. • Hex: #19F6FF. Six hex digits = red, green, blue channels. • RGB: rgb(25 246 255). Same idea, decimal. Hex is by far the most common in professional work. Keep a small palette (2–4 colours) and reuse it everywhere.
