Why this tool is useful
Peru (#CD853F) is a warm medium-brown with significant orange influence. It tests your display rendering of medium warm-earth tones, the range where many displays introduce unwanted orange casts. Archaeological photography, antique furniture retailers, and bronze sculpture photographers use peru as a monitor calibration reference for accuracy with warm brown earth-tone subjects.
