How to Find a Color from an Image

Finding a color from an image means selecting a visible part of an image and identifying the digital color value represented by that area. The result can commonly be expressed as a HEX, RGB or HSL color value.

This is useful when you want to reuse a color from a photograph, illustration, screenshot, logo, website or other visual asset.

An image may contain colors that you want to reuse in a website, presentation, illustration or brand design. Instead of trying to recreate the color by eye, a color picker can provide a precise value.

Extracting colors can also help you build a palette based on an existing image and maintain a closer visual relationship between the image and the surrounding design.

An image color picker allows you to select a location within an image and inspect the color information associated with that location.

The selected pixel or sampled area can then be represented using a color format such as HEX or RGB. Some tools also provide HSL and additional color information.

Start with the image that contains the color you want to identify. The image can be a photograph, screenshot, graphic, logo, illustration or another supported image format.

For the most useful result, use an image with enough resolution to clearly distinguish the area you want to sample.

Load or open the image in a color-picking tool that supports image color selection. The image should be displayed clearly so you can navigate to the relevant area.

If the tool supports zooming, use it when you need to select a small region or a particular pixel accurately.

Move the picker over the part of the image containing the color you want to identify. Select the relevant area and inspect the resulting color value.

For areas with gradients, shadows, textures or photographic detail, nearby pixels may have different values. Sample the area that best represents the color you actually want to reuse.

Once the desired color has been selected, copy its HEX, RGB or HSL value depending on where you plan to use it.

HEX is commonly convenient for recording web colors, while RGB or HSL may be useful when a project requires those specific representations.

HEX is a convenient format for recording colors found in an image. A selected color might produce a value such as #3366CC.

The HEX value can then be copied into CSS, a design tool or a palette document where compatible HEX notation is supported.

RGB describes the selected color using separate red, green and blue channel values. For example, the HEX color #3366CC corresponds to rgb(51, 102, 204).

RGB values can be useful when working with software or code that uses individual color channels.

Some color tools can also provide an HSL representation of a sampled color. HSL describes the color using hue, saturation and lightness.

HSL can be useful when you want to adjust the sampled color by changing its lightness or saturation while maintaining a related hue.

Photographs often contain many slightly different colors because of lighting, shadows, reflections and textures. A single object may therefore contain a range of related color values.

When sampling a photograph, select an area that represents the color you actually want to reproduce rather than assuming the entire object has one exact color.

Logos and flat graphics can be easier to sample because large areas may use consistent colors. Select a clean area away from shadows, gradients or anti-aliased edges when possible.

For brand assets, verify the extracted value against the official brand color information if exact brand consistency is required.

Screenshots can be useful when you want to identify a color used in a website, application or interface. Select the relevant area and copy the resulting color value.

Keep in mind that screenshots capture rendered pixels, so the sampled value may reflect effects such as transparency, gradients, overlays or display rendering.

Images are made up of pixels, and neighboring pixels do not always have identical values. Anti-aliasing, compression, lighting and texture can produce small differences between nearby areas.

If you need a representative color rather than a single-pixel value, sample several nearby areas and choose a value that best matches the intended design.

An image can provide inspiration for an entire color palette. Instead of selecting only one color, identify several important colors such as a dominant background color, accent color, darker supporting color and neutral.

Once the values have been collected, organize them into a palette and test how they work together in the intended design.

Extracted colors can be used in CSS for backgrounds, text, buttons, borders, illustrations and other interface elements.

Before using a sampled color for important text or controls, check its contrast against the surrounding background and make adjustments when necessary.

Colors sampled from an existing visual can help inspire a branding palette, but a sampled color should not automatically be treated as an official brand color.

If exact brand consistency matters, maintain a documented set of approved color values and use sampled colors as references rather than replacing the established values without verification.

The quality and characteristics of an image can affect the color value you sample. Compression, filters, lighting, transparency and color adjustments can change the pixels in an image.

For important production work, use the highest-quality source available and verify the extracted value in the final design environment.

One common mistake is sampling a shadow, highlight or edge instead of the main color area. Another is assuming that a photograph contains one exact value for an object.

It is also easy to copy a color without checking contrast or how it behaves against the background where it will eventually be used.

Choose a clear source image, zoom into the relevant area and avoid edges, shadows and reflections when they are not part of the intended color.

For larger designs, sample multiple related colors and test them together. Record the final HEX, RGB or HSL values so they can be reused consistently.

MartTools Color Tools can help you identify and work with color values for digital projects. Use the color information you obtain from an image as a starting point for CSS, palettes, graphics and other design work.

After identifying a color, you can use the related MartTools guides to learn how to choose supporting colors, convert between HEX, RGB and HSL and create a complete palette.
