ProToolBox

Random Color Generator (Free) — HEX, RGB & HSL

Set saturation & lightness → Generate color → see a large swatch, HEX, rgb(), and hsl() → Copy HEX or Copy CSS. No upload, no signup, no watermark.

Random color controls and results

UI accents, mood boards, “give me anything but gray” moments—each click is a new random hue with your saturation and lightness.

1 Saturation & lightness · 2 Generate color · 3 Preview swatch · 4 Copy values

Generated color

Recommended: 70% saturation & 50% lightness for punchy UI hues; lower saturation or raise lightness for pastels. Hue is random every time.

Presets:

Runs in this tab only—no server upload, no signup, no watermark.

What this is for

Random Color Generator (Free) — HEX, RGB & HSL builds values you can copy: free and instant, works in your browser, no account needed. Passwords, UUIDs, QR codes, barcodes—regenerate when rules or batch size change.

  • New batch when policy or environment shifts
  • Pin the tab during QA and fixture refreshes
  • Local generation
  • Staging seeds, mocks, and load-test data

Fit: Test inputs and assets without installing another app.

Bookmark this tab — the next “just need a color” moment is always mid-flow. Faster than opening a heavy design app.

When you need a fresh hue in seconds

Placeholder buttons, hero gradients, game jams, or teaching HSL. The loop stays obvious: tune S/L → generate → read the big HEX → copy into Figma, CSS, or a slide deck.

How it works

  1. Pick saturation and lightness (0–100%) or tap a preset.
  2. Click Generate color — hue is a random integer 0–359°; we convert HSL → sRGB → HEX.
  3. Copy HEX for one value or Copy CSS for color + background-color lines.
  4. Use the suggested text color as a starting point only—verify contrast for accessibility.

Privacy: Random colors are computed locally. We do not receive your saturation, lightness, or generated values.

FAQ

  • Is the hue really random? Yes — each click draws a new hue with Math.random; saturation and lightness follow your fields.
  • Why HEX and HSL? HEX is paste-friendly for CSS and tools; HSL matches how you steered the generator.
  • Is the text-on-color hint enough for a11y? No — it is a rough luminance shortcut. Use a contrast checker before shipping UI text.
  • Mobile? Yes — controls stack; the purple panel stays readable while you scroll.
