    Dark Harbor is a blue paint color with strong green undertones. It can look blue, teal, or green in certain lighting.

    In south-facing rooms with warm natural light, Dark Harbor will appear a bit lighter and warmer, leaning more green or teal.

    In north-facing rooms without much natural light, Dark Harbor will lean cooler, appearing as a dark blue.
