How to identify a text highlight color for a campaign

You have a text highlight color in a post, mockup, or screenshot, and need to reuse the same shade in campaign graphics. Guessing by eye can leave similar-looking colors with different values across your assets.

Use the Color Picker to sample a visible color and get its HEX, RGB, HSL, and other values. It works from anywhere on the screen in Chrome and Edge on a computer. Other browsers may offer a reduced version or none.

Find the highlight color

1. Open the Color Picker in Chrome or Edge on a computer. Keep the social post, design mockup, or source artwork visible on the screen.
2. Choose the best reference. If you have the original design file, use it instead of a screenshot or a social media preview. Those copies may have been resized or compressed.
3. Sample the middle of a broad, flat part of the highlight. Avoid the edges of letters, shadows, gradients, and thin borders, because neighboring pixels can have different colors.
4. Note the HEX value shown by the tool. You can also note RGB or HSL if that is the format your design editor uses. HEX is commonly written as a hash followed by six characters, such as #F2C94C.
5. Enter the value in the color field for the highlight in your campaign design. Save it as a reusable color swatch if your editor supports that, then check the finished graphic at its intended size.

For a campaign that will appear on phones, inspect an exported image on a phone too. A color value can be consistent while its appearance varies across screens, brightness settings, and display modes.

What the result means

The center of the highlight gives one steady value

This is likely the fill color you want to reuse. Save that value rather than relying on a visual description such as “gold” or “coral.” Those names can refer to many different shades.

Samples near the edge give different values

That is normal around text. Screen-rendered letter edges can contain blended pixels, a process called anti-aliasing, to make curves and diagonals look smoother. A shadow or outline can also add nearby colors. Use a flat area well inside the highlight, not the boundary between the background and the letters.

The color changes across the highlight

The design may use a gradient, texture, transparency, or a lighting effect instead of one solid fill. Decide whether you need one representative color or the full effect. To reproduce the appearance accurately, use the original design settings when available rather than sampling a single point and applying it to the whole area.

The value differs from your brand guide

You may be sampling a displayed version that has been resized, compressed, or altered by an overlay. Check the original artwork or a saved brand color swatch. A sampled color reports what is visible at that point, not necessarily the original color setting used to create it.

The highlight color is right, but the text is hard to read

Identifying the color does not automatically confirm that the text has enough contrast. Preview the combination at the size people will see it, including on a phone. If the text blends into the highlight, use a darker or lighter text color, or choose a more contrasting highlight while keeping the campaign style in mind.

How to fix it

1. Sample farther from the edge. Pick a point well inside the colored area, away from text, borders, and shadows. If there is no broad flat area, the design may not use a single color.
2. Use the original artwork. A screenshot or downloaded preview can contain compression artifacts or color changes. Open the editable source or a high-quality export and sample that instead.
3. Check whether the fill is transparent. A translucent highlight blends with whatever is behind it. The visible sampled color is the blend, not the underlying fill value. If you need the original fill setting, inspect the design file.
4. Try a supported browser. If the picker cannot select a color from the screen, use Chrome or Edge on a computer. The screen-wide color picker is not available in the same way in every browser, and this feature is intended for desktop use.
5. Compare the entered value carefully. Check that you copied all the characters and did not include a space or remove the leading # if the editor expects it. If the editor requests RGB instead, use the RGB values shown by the tool rather than typing the HEX value into the wrong field.

Keep the campaign color consistent

Record the color value somewhere your team can find it, along with a short label such as “campaign highlight.” Use the same saved swatch for later posts instead of sampling each new export. That prevents small differences from accumulating as graphics are revised.

When the campaign includes several formats, check the color in each final export. A square post, story, and profile graphic may be cropped or resized differently, which can change how the highlight looks even when the same value is used.
