The color(s) blue, green, red and white is/are claimed as a feature of the mark.
The mark consists of a three-dimensional, rectangular tri-color, representing (from top to bottom) a blue rectangular box stacked on top of a green rectangular box, stacked on top of a red rectangular box. The all-caps word STACKITS appears in white across the front plane of the "stacked" boxes, with the initial S at the top of the blue (topmost) box and the final S at the bottom of the (bottom most) red box. Two sides of the red box are visible, with the side (on the left) that runs to the vanishing point shaded to create depth/perspective. Two sides of the (middle) green box are visible, with the side (on the left) that runs to the vanishing point shaded to create depth/perspective. Three sides of the blue box are visible, the sides on the left and at the top running to the vanishing point shaded to create depth/perspective.
