Why this tool is useful
Sienna (#A0522D) is a warm muted reddish-brown derived from natural iron-oxide pigments. Fine art photographers, painting reproduction specialists, and museum collections use sienna as a monitor reference because it is a fundamental traditional pigment color. If sienna appears too orange or too dark red on your display, all warm-brown fine art and historical artifact photography will be systematically inaccurate.
