Frontend developers and designers regularly need to extract exact color values from websites — whether matching a client's brand from their live site, referencing a design system, or sampling a color from a mockup image. The fastest approach is a browser color picker that works on any rendered pixel without requiring DevTools knowledge or digging through source code.
Two Methods for Getting CSS Colors from Websites
Method 1: ColorPickPro (any rendered pixel)
ColorPickPro samples the actual rendered color at any pixel position on the screen. This includes:
- Text colors and background colors on any element
- Button and link colors
- Image pixels — useful for sampling from photos, icons, and screenshots
- Gradient midpoints (hover over any position in the gradient)
- Video frames (pause first, then sample)
The output is shown in HEX, RGB, and HSL simultaneously. Click any format to copy it directly to your clipboard, ready to paste into your CSS file.
Method 2: Chrome DevTools (declared CSS values)
DevTools shows the actual CSS declaration that produced a color, not a pixel sample. This is useful when you want to understand the exact variable, function, or notation the site is using.
- Right-click any element → Inspect
- In the Styles panel, find the relevant color property
- Click the colored square swatch next to the value
- The color picker popup shows HEX, RGB, and HSL representations
- Click the HEX/RGB/HSL display to switch formats and copy
hsl() functions, or oklch() values) rather than the resolved color.
Copy Any Color from Any Website in One Click
ColorPickPro gives you HEX, RGB, and HSL instantly. Works on images, gradients, and video.

| Format | Example | Best Use Case |
|---|---|---|
| HEX | #2563eb |
Static solid colors; most common; matches design tool exports |
| HEX with alpha | #2563eb80 |
50% opacity; shorter than rgba for transparency |
| RGB | rgb(37, 99, 235) |
When building rgba() transparency from a known HEX |
| RGBA | rgba(37, 99, 235, 0.8) |
Semi-transparent overlays, shadows, backgrounds |
| HSL | hsl(221, 83%, 53%) |
Design systems; easy to generate tints/shades by adjusting L% |
| HSLA | hsla(221, 83%, 53%, 0.9) |
Same as HSL + transparency |
Practical CSS Workflows
Matching a client's brand from their website
When a client gives you their URL but no brand guidelines, sample colors directly from their live site. Open their homepage, activate ColorPickPro, hover over the primary CTA button (primary brand color), the navigation bar background (secondary color), and any headline text. You'll typically capture 3-5 colors that represent the brand palette. Paste these into CSS custom properties at the top of your stylesheet:
:root {
--color-primary: #2563eb;
--color-secondary: #1e293b;
--color-accent: #f59e0b;
--color-text: #1a1a1a;
--color-background: #ffffff;
}
Sampling colors from a design mockup image
When given a Figma/Sketch export as a PNG or screenshot rather than direct design file access, drag the image file into Chrome (it opens as a local preview). Activate ColorPickPro and sample any color from the mockup image. The tool samples the rendered pixel regardless of whether it's a web page or a local image file.
Finding the exact shade from a competitor site
Competitive analysis often involves examining what color combinations established sites in your niche use. Sample their primary, secondary, and accent colors with ColorPickPro, then analyze the combinations for your own design reference. This is faster and more accurate than using DevTools to find the CSS file and locating the variable declaration.

HEX, RGB, HSL — all formats in one click. From any element, image, or gradient.

Modern CSS architecture uses custom properties (CSS variables) for color management. After sampling colors with ColorPickPro, the recommended workflow is to define all colors as custom properties and reference them throughout the stylesheet:
/* Colors sampled from client site using ColorPickPro */
:root {
/* Primary palette */
--blue-600: #2563eb;
--blue-700: #1d4ed8;
/* Semantic aliases */
--color-brand: var(--blue-600);
--color-brand-hover: var(--blue-700);
/* With transparency using rgba */
--color-brand-overlay: rgba(37, 99, 235, 0.1);
}
/* Usage */
.button-primary {
background-color: var(--color-brand);
}
.button-primary:hover {
background-color: var(--color-brand-hover);
}
.modal-backdrop {
background-color: var(--color-brand-overlay);
}
Generating Tints and Shades from a Sampled Color
Once you have a base color from ColorPickPro, you often need a full tint/shade scale. The fastest approach using HSL:
- Get the HEX from ColorPickPro
- Copy the HSL values shown in the extension (e.g.,
hsl(221, 83%, 53%)) - Generate the scale by adjusting the L (lightness) value:
:root {
/* Base: hsl(221, 83%, 53%) sampled from brand button */
--blue-50: hsl(221, 83%, 95%); /* Very light tint */
--blue-100: hsl(221, 83%, 90%);
--blue-200: hsl(221, 83%, 80%);
--blue-300: hsl(221, 83%, 70%);
--blue-400: hsl(221, 83%, 62%);
--blue-500: hsl(221, 83%, 53%); /* Base brand color */
--blue-600: hsl(221, 83%, 44%);
--blue-700: hsl(221, 83%, 35%);
--blue-800: hsl(221, 83%, 26%);
--blue-900: hsl(221, 83%, 17%); /* Deep shade */
}
This generates a complete color scale without any additional tools — just the base HEX value from ColorPickPro and HSL arithmetic.
Frequently Asked Questions
How do I get the CSS color value from any website?
Install ColorPickPro, activate it, hover over any element, and click to copy the HEX. Alternatively, Chrome DevTools → Inspect → Styles panel → click the color swatch. ColorPickPro samples rendered pixels (works on images and gradients); DevTools shows the declared CSS value.
What CSS color formats does ColorPickPro support?
HEX, RGB, and HSL — all shown simultaneously when you hover. Click any format to copy it. HEX is most common for static values; RGB is needed for rgba() transparency; HSL is best for generating tints and shades programmatically.
How do I convert a HEX color to RGB for CSS rgba()?
ColorPickPro shows the RGB values alongside HEX. Copy them and add alpha: rgba(37, 99, 235, 0.8) for 80% opacity. Modern CSS also accepts HEX with alpha channel: #2563ebcc where the last two hex digits represent opacity.
Can I pick colors from images and screenshots for CSS?
Yes. ColorPickPro samples any rendered pixel — including images, background images, and screenshots dragged into Chrome. Pause video content first, then sample any frame. This makes it useful for implementing designs from mockup images without design file access.
What is the difference between HEX and RGB for CSS?
They represent identical colors in different notation. Use HEX (#2563eb) for static solid colors — it's shorter and matches design tools. Use RGB/RGBA when you need transparency (rgba(37, 99, 235, 0.8)). Use HSL for design systems where you need to generate tint/shade variations by adjusting the lightness percentage.
How do I pick a color from a gradient in CSS?
ColorPickPro samples individual pixels, so you can hover over any point in a gradient to sample that specific color. The gradient start, middle, and end are each sampleable as independent colors. DevTools can also show the exact linear-gradient() or radial-gradient() declaration if you need the full function syntax.
Can ColorPickPro work on local HTML files?
Yes. Open your local HTML file in Chrome (drag it into the browser or use File → Open), activate ColorPickPro, and sample colors from the rendered page. This works on locally-served development environments as well — any page visible in Chrome is sampleable.
