              disableCloseOnSelect={true}
              multiple
              options={this.options}
              getOptionLabel={options => options.title}
              value={this.state.value}
              onChange={(e, techs) => {
                this.newValue(techs);
              }}
              renderInput={params => (
                <TextField
                  {...params}
                  variant="outlined"
                  placeholder={Technology}
                  fullWidth
                />
              )}
            ></Autocomplete>

You can use the tag CSS class to customize the tags as shown below.

import React from "react";
import TextField from "@material-ui/core/TextField";
import Autocomplete from "@material-ui/lab/Autocomplete";
import { withStyles } from "@material-ui/core/styles";

const CustomAutocomplete = withStyles({
  tag: {
    backgroundColor: "#a0a",
    height: 24,
    position: "relative",
    zIndex: 0,
    "& .MuiChip-label": {
      color: "#fff"
    },
    "& .MuiChip-deleteIcon": {
      color: "red"
    },
    "&:after": {
      content: '""',
      right: 10,
      top: 6,
      height: 12,
      width: 12,
      position: "absolute",
      backgroundColor: "white",
      zIndex: -1
    }
  }
})(Autocomplete);

export default function Tags() {
  return (
    <div style={{ width: 500 }}>
      <CustomAutocomplete
        multiple
        id="tags-standard"
        options={top100Films}
        getOptionLabel={option => option.title}
        defaultValue={[top100Films[13]]}
        renderInput={params => (
          <TextField
            {...params}
            variant="standard"
            label="Multiple values"
            placeholder="Favorites"
            margin="normal"
            fullWidth
          />
        )}
      />
    </div>
  );
}
