Just how big are these rainbows?

About Rainbow Blvd., from BoardGameGeek:

Build rainbows to make the city of Hopewell Springs beautiful while creating 3D masterpieces in Rainbow Blvd! In Rainbow Blvd. players are animal architects, tasked with completing blueprints and contracts with the goal of gaining the most prestige to become the next head architect at the rainbow factory. Rainbow Blvd. is played over a series of days (rounds). Each day begins with players acquiring blueprint cards that will reward them for building specific rainbow segments and arcs around the city. However, take on too many and there is a risk of losing prestige for uncompleted work. While the rainbow factory pays well, there are always opportunities for contracts to help. The 6 local color companies that produce the materials used by the rainbow factory want their hues to be used whenever possible. Each is willing to offer more prestige to whomever completes their various goals. The player who manages to collect the most prestige points before spring is the winner and new head architect at the rainbow factory! Rainbow Blvd. utilizes several fun mechanics including action selection, hand management, a time track, set collections, and more, resulting in a wonderfully beautiful experience around any game table!
