When custom icon used the fill fills the entire block

[Terceramayor]

When using a custom png icon, the rating color doesn't just fill the inside of the icon but the entire icon block:

<Rating type="custom" ratingImage={starIcon} ratingColor={'rgb(200,0,200)'} ratingCount={5} imageSize={16} showRating={false} tintColor={'rgb(0,100,200)'} readonly={false} startingValue={1.35} />

Just faced this issue as well...

Issue is the default star icon is actually a yellow outline, transparent content and white background outside.

So you need to add a white background to your image.
