Now that the electronics and software are set up, it's time to create the WLED pattern to light up the butterfly. There aren't any hard-and-fast rules here, and you can illuminate your butterfly however you like.

Personally, I like a blue butterfly with a shimmer of purple to give the effect of iridescence. This is inspired by butterflies such as the Common Blue and Holly Blue. Another common color pallet in nature is orange and red. However, you don't have to be limited by real life butterflies, you can pick whatever you like.

To create the effect for a Common Blue inspired butterfly, first you have to make some settings in the Colors tab in WLED. Pick a blue for color 1 and purple for color 2, then select Colors 1&2 in the pallet type list.

You can now switch to the effects tab and select your effect. I like the Blends effect.

Finally, in order to make your butterfly start with the same pattern when it's powered on, you need to save the setup as a preset.

In the Presets tab, click Create Preset, give it a name and click Save Preset. This will give it a preset ID. Remember this as you'll need it in the next step.

Go to Config > LED Preferences and scroll down. Near the bottom you'll find the Defaults section, and in this section, you'll see the option to Apply Preset x At Boot. Change the number to the ID of the preset you just created, and scroll back to the top to save the settings. Now, each time you power on your device, it'll start with the correct lighting.
