Why this tool is useful
Dark Cyan (#008B8B) is a deep teal that tests your monitor green-blue balance in the shadow tonal range. Marine and underwater photography extensively features dark cyan tones, and photographers in this field use it to calibrate before editing dive footage. If this screen appears distinctly more green or more blue than a true teal, your display needs color profile adjustment for accurate ocean and aquatic rendering.
