### The previous version in which this bug was not present was

_No response_

### Description

- Ripple around the Mat Checkbox and Mat Slider are not reaching the WCAG Non text contrast ratio of 3:1.
- Since the ratio is not met application is in a non complaint state for the mentioned components (Slider and Checkbox)

Steps to reproduce:
1. Open Stack Blitz url above
2. On the Preview the Mat Slider and Mat Checkbox are provided

4. The Ripple around the round slider color is not meeting the non text contrast ratio for WCAG AA compliance (3:1)
5. Similarly the Ripple around the Checkbox after selecting is not meeting the non text contrast ration for WCAG AA compliance (3:1)

### Expected Behavior

1. Both the Mat Slider and Mat Checkbox ripple color need to meet the non text contrast ratio (3:1) to be compliant since it is effecting Accessibility users.

Any help will take our application be more compliant for ADA and Accessibility
