A SVG recolouration demo, showing the power of vector graphics.

What is it?

SVG is an XML-based vector graphics language. This makes it easy for us to manipulate attributes such as individual colours and lines within the graphic.

This demo manipulates a SVG using a particular colour map in order to create many colour variations of the same sprite. Furthermore, the demo manages a filter over the overall colours in order to create night and day variations.

The Code

To illustrate my point, you can create a variation with the following code:

const svg = paint(svg, {
	primary : '#ff0000',
	secondary : '#0000ff',
	time : 13
});

This demo recolours one of the image templates to be a primarily red sprite with blue highlight colours as it would appear at 1 PM.

You can then add the SVG to the DOM the following code, for instance:

$('body').append(svg);

The future

This demo uses string replacement to change colours in an image which is fast but has limitations in terms of functionality.

In the future I may implement an XML parsing version in order to introduce advanced functionality such as manipulating attributes and creating lighting effects.
