Four free ways to find the exact HEX, RGB or HSL value of a colour on a site, a screenshot or a video.
You've seen a colour on a website and want its exact code for your own design, CSS or slides. Guessing from a screenshot rarely gets it right. Here's how to read the real value, starting with tools you already have.
Chrome and Edge: right-click the page and choose Inspect. In the Styles pane, click any small colour square (for example next to color or background-color). A colour picker opens. Click its eyedropper icon, then click anywhere on the page to sample that pixel. The picker shows the value, and its format switcher changes it between HEX, RGB, HSL and more.
Firefox: open the Page Inspector (right-click → Inspect) and use the eyedropper button in its toolbar. Click a pixel to copy its HEX code.
Good: nothing to install. Less good: it takes several clicks every time, and DevTools doesn't keep a history of your picks.
These tools work outside the browser too, for example in PDFs, apps and images.
If the colour is a CSS colour and not part of an image, the exact value is in the stylesheet. Right-click the element, choose Inspect, and look for color, background-color or border-color in the Styles pane. Many sites use variables like var(--brand). Click the variable to see its value. This gives you the colour the designer specified, which can differ from what a pixel shows when there's transparency, a gradient or a filter.
If you pick colours often, an extension saves you the DevTools clicks: one click or a keyboard shortcut, and the colour is copied.
