Attribute name for Title in Toolbar

## Expected Behavior

I was trying to override the color for the title text in the table, but I can't figure out the attribute name. Is there list of attribute names somewhere where it is possible to check and change them?

Also how do we change the icon color?
## Current Code

```
MUIDataTableToolbar: {
root: {
backgroundColor: "#1D252D",
color: "#CCCCCC"
},
TitleText:{
color:"#CCCCCC"
}
},
```

## Steps to Reproduce (for bugs)

1. Create MUI Theme
2. Apply Theme to table
