This is my <MyButton />
Component
import React from 'react';
import { withStyles } from '@material-ui/core/styles';
import Button from '@material-ui/core/Button';
const styles = theme => ({
button: {
backgroundColor: 'green',
"&:hover": {
backgroundColor: "red"
},
},
});
function MyButton(props) {
return (
<Button
className={props.classes.button} >
{props.text}
</Button>
);
}
export default withStyles(styles)(MyButton);
Currently, there is the default click effect on the button, brightening/lightening it up on click (see here: https://material-ui.com/demos/buttons/). However, I want the color of the "ripple" to be blue
when the button is clicked.
I tried
"&:click": {
backgroundColor: "blue"
},
and
"&:active": {
backgroundColor: "blue"
},
No luck though. How do I change the color of the ripple when the button is clicked?
Here's an example showing how to modify the button ripple for v4 (v5 example further down):
import React from "react";
import { withStyles } from "@material-ui/core/styles";
import Button from "@material-ui/core/Button";
const styles = theme => ({
button: {
backgroundColor: "green",
"&:hover": {
backgroundColor: "red"
}
},
child: {
backgroundColor: "blue"
},
rippleVisible: {
opacity: 0.5,
animation: `$enter 550ms ${theme.transitions.easing.easeInOut}`
},
"@keyframes enter": {
"0%": {
transform: "scale(0)",
opacity: 0.1
},
"100%": {
transform: "scale(1)",
opacity: 0.5
}
}
});
function MyButton({ classes, ...other }) {
const { button: buttonClass, ...rippleClasses } = classes;
return (
<Button
TouchRippleProps={{ classes: rippleClasses }}
className={buttonClass}
{...other}
/>
);
}
export default withStyles(styles)(MyButton);
The default opacity of the ripple is 0.3. In the example I have increased this to 0.5 to make it easier to verify that the ripple is blue. Since the button background is red (due to the hover styling), the result is purple. You'll get a different overall effect if you move to the button via the keyboard since the blue will be layered on top of the button's green background.

The main resource for the styling of the ripple is its source code: https://github.com/mui-org/material-ui/blob/v4.10.2/packages/material-ui/src/ButtonBase/TouchRipple.js

Here's a similar example for MUI v5:
import { styled } from "@mui/material/styles";
import Button from "@mui/material/Button";
import { keyframes } from "@emotion/react";
const enterKeyframe = keyframes`
0% {
transform: scale(0);
opacity: 0.1;
}
100% {
transform: scale(1);
opacity: 0.5;
}
`;
const StyledButton = styled(Button)`
background-color: green;
&:hover {
background-color: red;
}
&& .MuiTouchRipple-child {
background-color: blue;
}
&& .MuiTouchRipple-rippleVisible {
opacity: 0.5;
animation-name: ${enterKeyframe};
animation-duration: 550ms;
animation-timing-function: ${({ theme }) =>
theme.transitions.easing.easeInOut};
}
`;
export default StyledButton;

Here is the hack for Material-UI 4.9.10
Add a class to button and then add the below code to given class
Btn:{
"& .MuiTouchRipple-root span":{
backgroundColor: 'red!important',
opacity: .3,
},
},
