Welcome to MYX Icons vol. i!
Those are 100% free and licensed under MIT License icons, for use anywhere you want.
Colours can be easily modified in the SVG code.
To help you doing that I have placed comments in the code. My comments mark specific elements of an icon. To change colour of an element, all you need to do is type a hex (eg. #ffffff) of desired colour for the "fill" attribute that is localised in a line below my comment.
SVG can be edited with a text editor.
