Colla is a design studio from Milan specialized in UX and UI. 

"Colla" it's the italian word for glue, the adhesive substance used to stick things together. This visual identity plays a lot with colors and overlapping shapes that recall the idea of ​the adhesive sticker. These colored shapes are used to contain the logo and the services that the studio offers. In the logo there are the shapes of the C and the O that seem to be positioned one above the other just like adhesive stickers, taking up the concept of overlapping.
