  1. Create a CSS file to define the different classes and colors for the progress bar. Let's name it custom.css.
  2. Open the custom.css file and define the CSS classes and their corresponding colors. For example:
.o_progressbar .o_progress .o_progressbar_complete.o_progress_red {
background-color: #FF0000;
height: 100%;
.o_progressbar .o_progress .o_progressbar_complete.o_progress_yellow {
background-color: #FFFF00;
height: 100%;
.o_progressbar .o_progress .o_progressbar_complete.o_progress_light_green {
background-color: #00FF00;
height: 100%;
.o_progressbar .o_progress .o_progressbar_complete.o_progress_green {
background-color: #008000;
height: 100%;
After creating the CSS file, we need to provide the file into the file.

JS: To change the color of the progress bar, we can use the following code.

 /** @odoo-module **/
import { ProgressBarField } from "@web/views/fields/progress_bar/progress_bar_field";
import { patch } from "@web/core/utils/patch";
const { onMounted, useEffect } = owl;
patch(ProgressBarField.prototype, 'prgress_bar_custom',{
       var value = this.props.value;
       useEffect(() => this._render_value());
   _render_value: function (v) {
       var value = this.props.value;
       var max_value = this.state.maxValue;
       if (!isNaN(v)) {
           if (this.edit_max_value) {
               max_value = v;
           } else {
               value = v;
       value = value || 0;
       max_value = max_value || 0;
       var widthComplete;
       if (value <= max_value) {
           widthComplete = value/max_value * 100;
       } else {
           widthComplete = 100;
       $('.o_progress').toggleClass('o_progress_overflow', value > max_value)
           .attr('aria-valuemin', '0')
           .attr('aria-valuemax', max_value)
           .attr('aria-valuenow', value);
           $('.o_progressbar_complete').toggleClass('o_progress_red', widthComplete > 0 && widthComplete <= 40).css('width', widthComplete + '%');
           $('.o_progressbar_complete').toggleClass('o_progress_yellow', widthComplete > 40 && widthComplete <= 70).css('width', widthComplete + '%');
           $('.o_progressbar_complete').toggleClass('o_progress_light_green', widthComplete > 70 && widthComplete <= 90).css('width', widthComplete + '%');
           $('.o_progressbar_complete').toggleClass('o_progress_green', widthComplete > 90 && widthComplete <= 100).css('width', widthComplete + '%');

After creating the JS file, we need to add the file in the

'assets': {
   'web.assets_backend': [
Using this technique, we can change the color of the progress bar anywhere it appears in Odoo. By adjusting the value and width, we may customize the progress bar’s colors.
