How to change the color and position of data labels in Google Charts?

Question

Google

The project needed to build a simple pie chart, I used Google charts. Everything works great, but there is one problem. I don't know how to change the share signature options. These are the percentages that are on each piece of the chart. By default, they are white, plus they are positioned crookedly (they crawl out of the edges of the diagram).
Thanks in advance.
