"Metallic Color" as in ArtRage

Hi, welcome to our forum! I don't think there is an easy setting to get a metallic color in Clover Paint. You can try using the sand brush, it gives a sort of metallic texture if you use the right colors. You can play around with the colors by clicking on the sliders in the color swatch pallette. When you tap on the sliders new floating palettes pop up and you can adjust the colors with the sliders.

You might could find your own metallic texture and add it to a brush in the settings. You go into the settings and click on the plus sign by texture settings or color texture. That opens more options with a texture swatch. Click on the texture swatch and it will bring up a menu with several different textures. There is a plus sign at the bottom where you can add your own texture. This is a very complex program and mostly you just have to play around with all the settings and see what they do. I hope this helps. I'll post some screenshots to explain what I'm talking about.
