About the Octagon color filled icon
A single regular octagon is drawn in a thick even outline, its eight equal sides meeting at slightly softened corners around a completely empty interior. The blank center makes it a container as much as a shape, so it suits stop and warning signage, geometry and math teaching material, badge or achievement frames, flowchart and diagram building blocks, and placeholder shapes in wireframes.
The figure fills the canvas almost edge to edge with uniform stroke weight and no fill, keeping the eight-sided silhouette immediately readable. It pairs with hexagon, pentagon and triangle icons from the same geometry set. Drop a number or glyph inside it to turn the shape into a labeled marker.
This is the colour filled version of the octagon icon: a flat, solid-colour shape that stands out in dashboards, marketing pages and app tiles where the icon needs to carry colour meaning.
