The techniques presented in the previous sections covering layered and chained styles will allow you to create very complex styles. Starting from the last screenshot of the previous 3.4 Creating a Style in the Style Editor tutorial, we will replace the Reveal Original filter with a Simple Strokes to be able to add filters with different type of pins (Palette, Strokes).

We have also previously saved the Project file, for these special cases in which you want to make changes to the style. 

Switch to the Style Editor view and right-click the Reveal Original filter. Select the Simple Strokes filter from the Building Blocks/Simple styles to Replace the previous filter.

The filter will be replaced and the thumbnail will be recalculated immediately. Since you replaced the previous (Reveal original) filter, the new one is linked to the upper result layer on the right and keeps its blending mode and opacity. 

The Simple Strokes filter has 4 pins: 2 image pins, a strokes pin and a palette pin. So you do not have to switch between the Properties+Preview and the Styles pane, right-click the Simple Strokes filter and select the Palette Generator to insert it before. 

The Palette Generator filter will be automatically linked to the correct blue pin, with the default palette. The preview image will be rendered instantly. 

Double-click the Palette Genrator filter so you may change the colors. The Palette Editor will pop-up. Select a palette (e.g : Ocean Shores).

The Simple Strokes thumbnail will be updated, just like the image in the Properties+Preview pane. 

If a node has more than one input pin, the first one is always the primary input pin that must be connected. This is usually an image input pin, but not always. The other pins on the node do not need to be connected. The node will work fine without those other connections, but will use its default values for the pins that are not connected to any other nodes. For this reason, we choose to insert a Strokes direction filter before the Simple strokes filter node.

With the blue and purple pins connected to the respective filters, the Simple Strokes filter has changed, as you can see in the Properties+Preview pane. 

When you are done, you can switch back to the Compositing pane and see the result. The layers that you have created in the Style Editor will be listed in the Layer browser. You may change their properties and blending modes, as well as opacity by moving the sliders if you are not yet satisfied.

And the final result of this project is:
