The mark consists of two concentric circles centered above the word "Holocene", which appears in a Serif font and small caps. The inner circle consists of a color wheel, featuring various shades of grey, blue, orange and green. Two vertical lines intersected by a horizontal line overlay the color wheel carving it into six colored segments; the intersecting lines form negative space between the segments primarily in the shape of an "H" with the bar of the H extending horizontally in both directions and blending with the negative space between the concentric circles.
