Usually I work in Adobe Illustrator, but this soft is pricey and many people using free vector editor Inkscape instead. It's pretty easy to convert my vector drawings into svg or something like this so people on the other side could open them in Inkscape.
Only problem is they tend to ask me how to modify my drawings or do stuff in Inkscape :) So I made this.
In this video you can see few different ways of changing colors of shapes and strokes in Inkscape. Really simple operation, but it still could be useful, especially if you are new at this.
