Color Format Converter

Designers and developers constantly move colors between formats. A brand guideline lists HEX; CSS wants rgb(); a print vendor asks for CMYK. This free color converter accepts any of those inputs, shows a live preview, and outputs every equivalent — including HSL for intuitive hue edits and ready-to-paste CSS strings.

Whether you need a hex color translator for a landing page or an rgb converter for a Figma handoff, edit one field and the rest sync instantly. All math runs in your browser; nothing is uploaded.

Web colors are often written as six-digit hex: #3B82F6. To convert hex rgb or convert from hex to rgb, split the string into three pairs and parse each as base-16:

#3B82F6 → R=0x3B (59), G=0x82 (130), B=0xF6 (246) → rgb(59, 130, 246)

Searches like hex into rgb, change hex to rgb, hexadecimal to rgb converter, and color hexadecimal converter all describe the same operation. Short three-digit hex (#F00) expands by doubling each character to #FF0000 — supported in the editor above.

Reverse direction: a color converter rgb to hex or color hex code converter formats each 0–255 channel as two hex digits. Use the RGB tab, and the hex field updates automatically.

Screens use additive RGB (red, green, blue light). Commercial printing uses subtractive CMYK (cyan, magenta, yellow, black ink). To convert rgb to cmyk or run an rgb cmyk conversion, each channel is normalized to 0–1, black (K) is derived from the darkest channel, and C/M/Y are computed from the remaining components.

Example: rgb(59, 130, 246) → approximately cmyk(76%, 47%, 0%, 4%). Phrases like rgb color to cmyk, rgb color cmyk, and cmyk color conversion refer to this transform. Pure black rgb(0,0,0) maps to cmyk(0%, 0%, 0%, 100%).

Important: RGB covers a wider gamut than CMYK. Neon greens and saturated blues often shift when printed — the converted CMYK is a mathematical approximation, not a press proof. Always request a physical proof for brand-critical work.

Print assets sometimes arrive as CMYK percentages. To convert cmyk to rgb or move cmyk into rgb for web use, the inverse formula reconstructs red, green, and blue from cyan, magenta, yellow, and key (black). Edit RGB in the tool and read CMYK output, or start from hex and verify the print values.

Cmyk conversion in both directions helps when a packaging PDF lists ink percentages but the companion website needs matching CSS. Paste the hex from your brand book, confirm CMYK, then copy rgb() or hsl() strings from the output panel.

There is no direct hex-to-CMYK formula — hex decodes to RGB first, then RGB converts to CMYK. A hex to cmyk workflow therefore means: parse hex → rgb → cmyk. The converter above does both steps automatically when you type a hex code.

A hex colour converter (British spelling) and a color converter hex tool serve the same role: translate between human-readable hex and the numeric formats your stack expects. HSL appears as an intermediate editing mode — useful when you want to lighten a brand blue without touching three separate RGB sliders.

Many searches ask for a cmyk to pantone converter, cmyk into pantone, or convert cmyk to pantone color. Pantone spot colors are proprietary named inks with published Lab values — accurate matching requires Pantone's licensed libraries (Connect, Color Bridge guides, or Illustrator's Pantone+ books).

This color code converter outputs standard process CMYK percentages derived from RGB. It does not return an official Pantone code (e.g. Pantone 286 C). For prepress:

• Use Pantone Color Bridge to find the nearest coated/uncoated swatch to your CMYK values.
• Specify spot Pantone when brand guidelines require it — CMYK is a four-color process fallback.
• Convert screen hex → CMYK here first, then compare in professional color-management software.

Cmyk to pantone color conversion in production workflows always involves a measured delta-E search against Pantone's catalog — not a single deterministic formula. Treat CMYK output here as a starting point for print discussion, not a Pantone replacement.

Beyond raw numbers, the tool outputs copy-ready CSS: hex, rgb(), rgba(), hsl(), and cmyk(). HSL separates hue (0–360°), saturation (0–100%), and lightness (0–100%) — ideal for hover states (hsl(217, 91%, 45%) for a darker blue) without guessing RGB offsets.

Eight-digit hex #RRGGBBAA supports alpha transparency. The preview swatch updates as you edit any channel, so a color converter session doubles as a quick sanity check before committing tokens to a design system.

Web: Store brand colors as CSS custom properties in hex or hsl. Convert once, paste into :root, reference with var(--brand-blue).

Print: Design in RGB for screen mockups, then convert rgb to cmyk before sending to the printer. Expect gamut shifts on saturated colors.

Handoff: When a developer receives hex and a print designer needs CMYK, one shared link to this converter avoids back-and-forth spreadsheet errors. This is a single-color rgb converter — not a batch rgb to cmyk image converter. For whole images, use Photoshop, GIMP, or a dedicated prepress RIP that applies ICC profiles per pixel.
