Here i work with 3 Valves , each valve control an other color. So i´m able to create such Colorful splashes. The color of the top shape is Purple, but it work not good with the green background. I have some splashes with 4 shapes on the spout, but the shapes are not good enough.
When you want to see my Setups you can take a look at my Homepage (in German ) or you can go on my Flickr stream, here i have write some Word in English about my stuff.
