For this tutorial, we are going to use the Chrome browser.
This method works on any other modern browser available.
Open the website you want to sample.
Next, right-click and choose inspect.
By default, the elements tab will display.
Under the styles and element style selector, add color with the value of red or any color.
The color value will then be used as a color picker.
Using the color picker, point your cursor anywhere on the webpage to select the color.
You can generate HEX, RGBA, and HSLA color codes.
