Is your feature request related to a problem? Please describe.

When I customized bacgkroundColor or color to dark, It's hard to see a [LoadingElement] since loading color is fixed with text.basic.

Describe the solution you'd like
I think providing a loading styles props would be great. And how about making the [LoadingElement] have the same color as the text color?
