The specific steps include: 1. Press F12 or right-click to check the element to open DevTools; 2. Click on the color square to start the selector; 3. Drag the slider or enter the value to adjust the color and preview it in real time; 4. Use the historical label to reuse the colors to maintain consistency; 5.

Chrome DevTools' color selector is actually quite practical, especially when debugging web styles, which can quickly adjust color values. Many people know that it exists, but are not skilled enough, or they do not know its hidden skills. This article will talk about how to really use this tool.

How to open the color selector
To use the color selector, you must first open Chrome DevTools (shortcut key F12 or right-click the page element to select "Check"). Then find the properties with color in a CSS style, such as color
, background-color
, or border-color
. Click on that color square and the color selector will pop up.
At this time you can see:

- Color panel (can be dragged to select colors)
- HEX, RGB and HSL representations of the current color
- Historical color records
If you want to quickly switch to other formats, just click on the value section to switch the display method.
How to use the color selector to debug colors in real time
The color selector is not only used to see the colors, but also used for real-time debugging. You can drag the slider on the Color panel to change the color, or you can manually enter HEX, RGB, or HSL values. Changes will be reflected immediately on the page, making it easier for you to view the results instantly.

Some tips:
- Hold down the left mouse button and drag the color slider to fine-tune the color
- After entering the value, press Enter to trigger the update (some versions require it)
- Click the contrast area between "Initial Color" and "New Color" to quickly switch the current color status
If you are optimizing the color scheme, this feature is particularly useful and you can see visual changes without repeatedly modifying the code.
A small trick of historical colors and color pickers
There is a "History" tab on the right of the color selector, which will save the colors you have used recently. This is very helpful for maintaining color consistency. For example, if you use the same blue color in multiple places, you can directly choose from history without having to re-choose it.
Another feature that is easily overlooked is the "color collector". There is a straw icon at the bottom of the color selector interface. After clicking, the mouse will become a color selector. You can move it anywhere on the page and pick up the color of that dot with just one click.
This is very convenient when adapting UI or restoring design drafts, especially when you are not sure what color a certain element is using.
Basically that's it. Although the color selector is just a gadget, it can save a lot of time after using it. The key is to try it more and be familiar with various operation methods. Gradually, you will find that it is more flexible than you think.
