How to use the fill attribute of input in elementUi?

the default click is blue. I want to change the color, but there is no effect after adding it in from. How can I change it?

       <el-form-item label="" prop="resource" fill="red">
          <el-radio-group v-model="ruleForm.resource">
            <el-radio label=""></el-radio>
            <el-radio label=""></el-radio>
          </el-radio-group>
        </el-form-item>
