Generate, convert, and copy HEX, RGB, and HSL color codes with live preview. Edit any format and all three stay in sync — RGB 0–255, HSL hue 0–360°, random color, and one-click copy for CSS, Figma, Tailwind, and brand documentation.
Also try the CSS Gradient Generator, Color Palette Generator, and more in Utility tools.

Color preview
HEX: #2D6CDF
RGB: rgb(45, 108, 223)
HSL: hsl(219, 72%, 53%)
Use HEX for design tools, RGB for CSS rgba-based workflows, and HSL for shade/lightness adjustments.
A color code generator converts between web color formats so designers and developers share one exact color without manual math. Muxgen keeps HEX, RGB, and HSL synchronized as you type or adjust channels, with a live swatch and format-specific copy buttons.
Use it for CSS variables, component libraries, QR brand colors, and style guides — everything runs in your browser with no uploaded palette data.
Three steps from input to clipboard-ready color strings.
Enter HEX (blur to sync), or adjust R/G/B 0–255 or H 0–360 with S/L 0–100% — default #2D6CDF.
Fine-tune channels while the swatch updates, or click Random color for exploration.
Copy HEX, RGB, or HSL into Figma, CSS, Tailwind arbitrary values, or token docs.
Every input in the tool panel and what it updates.
Six-digit hex with optional # — syncs on blur when valid; invalid entries keep last good RGB-derived hex.
Red, green, blue numeric inputs — each change recalculates HEX and HSL immediately.
Hue 0–360°, saturation and lightness 0–100% — ideal for lightness tweaks without hue drift.
Large swatch plus summary lines for normalized HEX, rgb(...), and hsl(...).
Cryptographically random bytes when supported — sets all formats from one click.
Separate clipboard buttons with brief Copied! feedback per format.
When to use each output from the copy buttons.
Compact, case-normalized uppercase in copy — default design-system canonical format for many teams.
Direct mapping to CSS color and canvas APIs — channels clamped 0–255 in output string.
Human-friendly adjustments to saturation and lightness for UI states and themes.
Bidirectional updates from whichever control you edit.
Valid six-digit hex on blur runs hexToRgb then rgbToHsl — preview and copy strings update.
Any R/G/B change runs rgbToHex and rgbToHsl — single source for pixel-accurate colors.
HSL changes run hslToRgb then rgbToHex — hue wraps modulo 360 in the conversion math.
Where accurate color codes speed up handoff.
Copy HEX into --color-primary and HSL variants for hover states in the same file.
Share uppercase HEX with designers; developers paste matching rgb() in components.
Lock foreground/background hex before opening Canva or Adobe QR generators.
Pick endpoint colors here, then open CSS Gradient Generator for multi-stop backgrounds.
The Color Palette Generator builds multi-color harmonies; this page converts one color across HEX, RGB, and HSL.
Pick stop colors here, then open the CSS Gradient Generator or paste hex into Canva and Adobe QR code tools for branded scans.
Controls aligned with the live color code component.
One color, three formats — always in sync from whichever control you edit.
Large panel reflects normalizedHex — invalid hex falls back to RGB-computed hex.
RGB 0–255 and HSL bounds enforced on every sync — consistent copy output.
Explore palettes fast with Web Crypto random bytes when available.
HEX, RGB, and HSL each have dedicated copy with 2s confirmation state.
Instant conversion for design-dev handoff without accounts or plugins.
Typical workflows where fast conversion saves time.
Define button, alert, and link colors with exact HEX and CSS rgb/hsl variants.
Paste into stylesheets, @theme tokens, or arbitrary value brackets.
Export all three formats for style guides and design-system README files.
Iterate HSL lightness on accent colors for contrast and hierarchy tests.
Designers share HEX; engineers copy matching rgb() without manual math.
Randomize and tweak channels during early wireframe color exploration.
Pick the right generator for one color vs palettes vs gradients.
This page is single-color conversion; Color Palette Generator builds multi-swatch schemes in image tools.
Gradients need two or more stops — pick each stop’s hex here first.
QR generators consume hex for modules and backgrounds — convert brand colors here first.
Teams often store HEX in tokens; CSS may use rgb() — this tool keeps both aligned.
Hover and disabled states often adjust L% only — edit HSL without re-picking hue.
Muxgen does not save your colors — copy values into your repo or design file.
Terms designers and developers search when converting codes.
Hexadecimal color notation — six digits after # representing RGB byte pairs.
Red, green, blue additive model — each channel 0–255 in this tool.
Hue, saturation, lightness — cylindrical model friendly for theme tuning.
Uppercase #RRGGBB shown in preview and Copy HEX — derived from valid input or RGB fallback.
Values forced into valid ranges so output strings never exceed CSS limits.
Named color variable (e.g. primary-500) whose value is often stored as HEX.
Keep tokens and implementation output consistent across teams.
Pair text and background colors with WCAG contrast checkers before shipping UI.
Store HEX or HSL as source of truth in tokens — convert here for other consumers.
Label tokens by role (primary, success, danger) not only by hex value.
Keep hue constant and step lightness for hover, active, and disabled variants.
Edit one format per tweak session — the tool syncs all three to prevent manual math errors.
CSS modules may want hsl(); Android XML may want hex — use the matching copy button.
Habits that pair with the converter controls.
Six-digit hex applies on blur — typing #ABC expands shorthand to #AABBCC internally.
Paste marketing HEX, then copy hsl() for CSS theme variables in one pass.
Hit Random color repeatedly, copy HEX when a direction clicks, then fine-tune L% in HSL.
Dark-on-light QR scans best — test contrast after copying hex into QR generators.
Reset mentally to #2D6CDF (rgb 45, 108, 223) — the tool’s initial sample color.
When you need five harmonious colors, open Color Palette Generator with your chosen base.
HEX, RGB, HSL — conversion, limits, random color, copy output, and vs palette tools.
