Update fragment_onboarding.xml

The original text color of the component is '#FFFFFF', and the contrast between the text color ('#FFFFFF') and the background color ('#FF5722') does not meet the standard of WCAG 2.1. In other words, this color cannot be easily seen by everyone. So, to solve this problem, our team designed a tool that can automatically detect and repair such problems. The test report and recommended replacement colors ('#282828') are as follows:

The figure on the left is the original page, the figure on the right is the repaired page, and the figure below is the problem detection report.

Your test are bugged? #FF5722 is orangeish not greenish. Orangeish is/are only select border of element(s).

Also few test pass #FFFFFF on #FF5722: Normal Text WCAG AA: Fail ❌ WCAG AAA: Fail ❌ Large Text WCAG AA: Pass ✅ WCAG AAA: Fail ❌ Graphical Objects and User Interface Components WCAG AA: Pass ✅

I agree #FFFFFF fail test on greenish #3EAE56: Normal Text WCAG AA: Fail ❌ WCAG AAA: Fail ❌ Large Text WCAG AA: Fail ❌ WCAG AAA: Fail ❌ Graphical Objects and User Interface Components WCAG AA: Fail ❌

IMO black looks bad on green, maybe better use darker green #376236 for white.
