How to Change the Highlight Color in Adobe Acrobat for More Effective PDF Reviews

To change the highlight color in Adobe Acrobat, select the highlight tool, open the color picker in the Comment toolbar, and choose a new color before you mark text. If you already highlighted something, right-click the highlight, choose Properties, pick a color, and save it as your new default if you want. That is the quick fix. No magic. No secret menu. Just a tiny color square hiding in plain sight.

Why highlight color matters more than it should

PDF reviews can get messy fast.

One person highlights every typo in yellow. Another uses yellow for key points. Someone else uses yellow because they like sunshine. Now your PDF looks like a highlighter exploded on it.

It drives me crazy that one tiny color choice can add 10 extra minutes to a review. But it can. Color is a simple code. It tells people what to do next.

Use color like a traffic light:

• Yellow: Read this or check this.
• Red: Fix this now.
• Green: Approved or good to go.
• Blue: Question for the team.
• Purple: Legal, compliance, or special review.

Simple colors. Fewer arguments. Happier PDFs.

How to change the highlight color before highlighting

This is the cleanest way. Pick your color first. Then start marking text.

1. Open your PDF in Adobe Acrobat.
2. Click All tools or Tools, depending on your version.
3. Choose Comment.
4. Select the Highlight Text tool.
5. Look for the small color square in the toolbar.
6. Click it.
7. Choose your highlight color.
8. Drag over text to highlight it.

That is it. Your next highlight should use the new color.

If you do not see the color square, click the highlight tool first. Acrobat sometimes hides options until a tool is active. Helpful? Not really. Classic Acrobat behavior.

How to change the color of an existing highlight

Already marked half the document in the wrong color? Been there. No need to redo it.

1. Click the highlight you want to change.
2. Right-click it.
3. Select Properties.
4. Go to the Appearance area.
5. Click the color box.
6. Pick a new color.
7. Click OK.

On a Mac, use Control-click if right-click is not set up.

You can also open the Comments panel, select a comment, and adjust its properties from there. This helps when your PDF has lots of notes.

How to make your favorite highlight color the default

This is the setting that saves your sanity.

If you always use green for approval, make green the default. Then Acrobat stops jumping back to yellow like a stubborn little goblin.

1. Create one highlight in your preferred color.
2. Right-click the highlight.
3. Choose Properties.
4. Pick the color you want.
5. Check Make Properties Default, if you see it.
6. Click OK.

Some Acrobat versions use slightly different wording. You may see Make Current Properties Default. Same idea. Click it.

Now new highlights should use that color until you change it again.

A simple color system for PDF reviews

Do not use 12 colors. Nobody will remember them. You are reviewing a PDF, not building a candy wall.

Start with four colors:

• Red: Must change.
• Yellow: Needs attention.
• Green: Approved.
• Blue: Question or discussion.

This works well for business reports, school papers, legal drafts, manuals, and client proposals.

Here is a quick example.

A marketing manager reviews a 16-page brochure. She uses red for wrong prices, yellow for awkward wording, blue for questions to the designer, and green for approved sections. The designer opens the file and knows what to fix first. No long email. No guessing game. No “wait, what does orange mean?” chaos.

How to change highlight color in Adobe Acrobat Reader

Good news. You can usually change highlight colors in Adobe Acrobat Reader too.

The steps are almost the same:

1. Open the PDF in Acrobat Reader.
2. Select Comment.
3. Choose Highlight Text.
4. Click the color option in the toolbar.
5. Pick your color.

If the PDF is locked or protected, you may not be able to comment. In that case, Acrobat is not being rude on purpose. Well, maybe a little. The file owner may have blocked editing and comments.

What if the color option is missing?

Acrobat has different layouts. The button may move. This is annoying, but fixable.

Try these quick checks:

• Select the highlight first. The color option may appear only after selection.
• Open the Comment tool. Highlight colors live there.
• Right-click an existing highlight. Then choose Properties.
• Check the Comments panel. Select the comment and review its options.
• Update Acrobat. Old versions can show older menus.

If you are using the new Acrobat interface and feel mildly betrayed, try switching views. Some users prefer the older layout because the tools are easier to spot.

Tips for better PDF reviews with highlight colors

Color helps, but only if people agree on what it means.

Try these rules:

• Set a color key at the start. Add it in the first comment.
• Use fewer colors. Four is plenty for most teams.
• Do not mix meanings. Red should not mean “urgent” on page 2 and “maybe” on page 8.
• Add comments when needed. A red highlight alone may not explain the fix.
• Use names in comments. Say who needs to act.

A neat trick is to add a short note on page one:

Color key: Red = fix, Yellow = review, Blue = question, Green = approved.

That one sentence can save a team from a 14-message email thread.

Can you change multiple highlights at once?

Sometimes, yes. But Acrobat can be picky.

Open the Comments panel. Select more than one highlight if your version allows it. Then try changing the properties. If that does not work, you may need to update each highlight one at a time.

Annoying? Very. Especially in a 50-page file.

For future reviews, set your default color before you start. That avoids cleanup later.

Best colors for different review jobs

Here are easy setups you can steal.

For editing text

• Red: Error.
• Yellow: Reword.
• Blue: Fact check.
• Green: Approved.

For legal review

• Red: Risk.
• Purple: Legal clause.
• Blue: Client question.
• Green: Accepted.

For studying

• Yellow: Main idea.
• Pink: Definition.
• Blue: Example.
• Green: Memorize.

Pick colors that feel natural. Also think about contrast. Pale yellow on a bright screen can be hard to see. Red may feel too intense for gentle notes. Blue is great for questions because it feels calm.

Final tip: treat colors like labels

Changing the highlight color in Adobe Acrobat is easy once you know where the color box is hiding. The real win is using colors with purpose.

Before your next review, choose a simple color code. Tell the team. Set your default highlight color. Then mark the PDF with less fuss.

Your future self will thank you. Your team will thank you. And your PDF will look less like a neon crime scene.
