A distinct icon style has been created for Helsinki. The icon style is based on the Helsinki framed logo and the design language of the wave motif. Here are some examples from the icon image library.
Some illustrative icons are similar to actual pictograms for signs even if the use is different. Same similarity can be seen with user interface icons, which are part of user interface design (HDS).
These image icons may be used as illustrations to add visual elements to presentations or publications, not as official signs.
