Custom colors

Color Tool <https://material.io/resources/color//>_ is the best way to generate new themes, just choose colors and export as Android XML, the theme file must look like:

<!--?xml version="1.0" encoding="UTF-8"?-->
<resources>
  <color name="primaryColor">#1de9b6</color>
  <color name="primaryLightColor">#6effe8</color>
  <color name="primaryDarkColor">#00b686</color>
  <color name="secondaryColor">#263238</color>
  <color name="secondaryLightColor">#4f5b62</color>
  <color name="secondaryDarkColor">#000a12</color>
  <color name="primaryTextColor">#000000</color>
  <color name="secondaryTextColor">#ffffff</color>
</resources>

Save it as my_theme.xml or similar and apply the style sheet from Python.

apply_stylesheet(app, theme='dark_teal.xml')

Light themes

Light will need to add light_secondary argument as True.

apply_stylesheet(app, theme='dark_teal.xml', light_secondary=True)
