Using Distort and Ripple Filters to make a Sun in Inkscape
There are several ways to make a sun using Inkscape depending on how stylized you want the object to be. I started with the Polygon tool. Make sure Fill and Stroke are set for the same color.
Distort is a menu and Torn Edges a filter. Ripple is under Distort.
Now you have something like a son now you can reset the stroke to yellow or orange if you want to but first duplicate a sun make it larger and move it down to be the bottom layer and you can get this!
Only two vector objects but 4 colors in the result! I probably should tweak the width and height or maybe give this a dark background. You could change the red centre to another color if you want to.
If I get some feedback I may put this up on my #deviantart
