Linear icons are great because they do not close the background and allow you to see the content "under them". Their other advantage is a certain lightness of appearance. Visually, they take up less space and do not load the interface. The Red Line set for 7tsp is made in red shades and will be perfectly combined with an aggressive design. For example, gamers will like it, whose setup is made in black and red style (adherents of msi, as an option).
