3 Random Color Generator Tools, Compared Honestly
Manesh Jayawardhana

You need a batch of random colors — for a design mockup, a test dataset, or just visual inspiration — with hex and RGB values you can copy directly.
Most random color generators do the same basic job well; the differences show up in batch size, extra formats like HSL, and whether the free version comes with ads pushing a premium upgrade.
How to judge a random color generator tool
Generates in batches. A handful of colors at once beats clicking “regenerate” repeatedly for a single swatch.
Shows multiple formats. HEX and RGB cover most needs, but HSL is useful for anyone doing color adjustments by hue and saturation.
One-click copy. Each swatch’s value should copy to your clipboard without extra steps.
No signup for a quick batch. Generating random colors is a one-off, instant task.
The comparison
| Tool | Best for | Free tier | Watch out |
|---|---|---|---|
| Comment Picker | Large batches (up to 100 colors) | Free, no signup | Ads shown unless you upgrade to Premium |
| Color Designer | Simple HEX/RGB/HSL batches (up to 40) | Free, no signup | Ads present, with a paid tier to remove them |
| MyRandomGenerator | Filtered types (bright, pastel, vivid) plus harmony modes | Free, no signup | Batch capped at 99 colors |
| Random Color Generator | Fast batch with HEX and RGB shown side by side | Free, no signup | No color-type filter or harmony mode |
Facts checked August 2026; tools change their plans.
Comment Picker
Comment Picker generates HEX, RGB(A), and HSL colors in batches up to 100 at once, with no signup required for unlimited use.
It isn’t for someone who wants an ad-free experience — the free version displays ads, with a Premium upgrade available to remove them alongside other features.
Color Designer
Color Designer lets you generate anywhere from a single color up to forty at once, showing HEX, RGB, and HSL values for each, with a slider to control batch size.
It isn’t for someone avoiding upsells — ads are prominent on the page, with repeated prompts to go ad-free through a paid subscription.
MyRandomGenerator
This tool adds real flexibility: filter by Bright, Dark, Vivid, or Pastel color types, and optionally apply a color harmony mode — complementary, triadic, tetradic, analogous, or monochromatic — built from a random base color, generating up to 99 at a time.
It isn’t for someone who wants the absolute simplest interface — the added filters and harmony options are genuinely useful but add more decisions than a bare “give me random colors” tool.
Random Color Generator
Our tool generates a batch of random colors with HEX and RGB values shown side by side, and you can copy any swatch to your clipboard with one click — entirely in your browser.
A real limitation: there’s no color-type filter or harmony mode — every color is fully random, without the option to bias toward pastels, vivid tones, or a coordinated scheme.
Which one to pick
If you want a fast, no-ads batch of random colors with HEX and RGB, use our Random Color Generator.
If you want the largest possible batch in one generation, use Comment Picker.
If you want filtered color types or a built-in harmony mode, use MyRandomGenerator.
If you’re comparing HSL values alongside HEX and RGB, use Color Designer.
How to do it with Random Color Generator
- Open the Random Color Generator.

If you want colors that work together rather than purely random ones, our Color Wheel Tool explores complementary, triadic, and analogous schemes starting from any hex color, with click-to-copy swatches.
Frequently asked questions
Is there a free random color generator that doesn’t need an account?
Yes. Our Random Color Generator and all three alternatives here generate colors without requiring signup.
What’s the difference between HEX, RGB, and HSL?
HEX is a six-digit code representing red, green, and blue values in hexadecimal (like #FF5733). RGB expresses the same values as three numbers from 0-255. HSL describes a color by hue, saturation, and lightness instead, which is often more intuitive for adjusting a color’s shade or intensity, as defined in the CSS Color Module specification.
Why would I need truly random colors instead of a curated palette?
Truly random colors are useful for testing — checking how a UI handles arbitrary color values, generating placeholder data, or sparking unexpected design inspiration you wouldn’t land on by picking colors yourself.
Final thought
For a quick batch of random colors to copy and use, pick the generator that gets out of your way fastest — save the filters and harmony modes for when you specifically want a coordinated palette rather than pure randomness.
