Unicons Monochrome is a set of 200+ Monochrome style icons that are totally free to use. The icons are designed by the guys at IconScout.
You can easily change the color of an icon according to your color palette. Simply apply the primary color and we will generate other color shades automatically.
Icons are available in top categories (for example, User Interface, Business, Shopping, Medical) and they are carefully crafted in a 24px grid to have consistency on all kinds of display.
Icons are available in SVG files. Developers can use them directly in their code by including a CSS file in the head section of a web page.
