Can not change the hint color of the v-text-field and v-select in Node-RED

Hi, sir

Here is my code, and it is strange that the hint color is changed to orange in VPlay, however the hint color remains the same in my dashboard2.

Pls find this picture for the difference:

<template>
  <div class="wrapperPara" ref="wrapper">
    <v-card v-for="(parameter,index) in item.paraItems" :key="index" ref="cards" class="cardPara">
      <v-card-text class="card-contentPara">
        <div class="containerPara">.
          <div class="leftPara">
            <i class="iconPara">{{ item.houseIcon }}</i>
          </div>
          <div class="middlePara">
            <div class="titlePara">{{ parameter.name }}</div>
            <div v-if="parameter.name!=='variable' && parameter.name!=='signal' "class="control-row">
              <button class="btnPara" :style="{ height:'25px', backgroundColor: parameter.isFixedValue ? '#90a4ae' : 'rgb(0, 204, 255)'  }"  @click="onFixed(index)">FIXED VALUE</button>
              <button class="btnPara" :style="{ height:'25px', backgroundColor: parameter.isFixedValue ?  'rgb(0, 204, 255)':'#90a4ae'  }"  @click="onVariable(index)">VARIABLE</button>
            </div>
            <div v-if="(parameter.name!=='variable' && parameter.name!=='signal') && parameter.isFixedValue===false " class="control-row">
              <v-text-field  v-model="parameter.value" hint="Please input the value" persistent-hint class="paramsPara"></v-text-field>
              <v-text-field readonly class="paramsPara2">
                mm/s
              </v-text-field>
            </div>
            <div v-else class="control-row">
              <v-select  hint="Plsease select the item" persistent-hint :items="variableNames" class="paramsPara">
              </v-select>
