Conversor de Unidades e Cores CSS

Entendendo cores e unidades CSS

Formatos de cor HEX, RGB e HSL

CSS suporta vários formatos de cor. <strong>Cores HEX</strong> usam notação hexadecimal de seis caracteres.

<strong>RGB</strong> usa valores decimais de 0 a 255 para cada canal.

<strong>HSL</strong> é o mais intuitivo para designers.

CSS Named Colors

CSS provides 147 named colors like coral, steelblue, and rebeccapurple. While convenient for prototyping, named colors offer limited precision. Converting a CSS color name to HEX or RGB gives you exact values you can fine-tune for production use.

CMYK para design de impressão

<strong>CMYK</strong> é o modelo de cor padrão para impressão.

HSV em ferramentas de design

<strong>HSV</strong> é o modelo de cor nativo em ferramentas como Photoshop, Figma e Sketch.

PX vs REM: Unidades CSS explicadas

<strong>Pixels (PX)</strong> são unidades absolutas. <strong>REM</strong> é relativo ao tamanho da fonte raiz.

Divida pixels por 16 para obter valores REM.

<strong>Unidades EM</strong> são relativas ao tamanho da fonte do elemento pai, diferente do REM que referencia a raiz.

• 1rem = 16px (default browser setting)
• 1em = parent font-size (context-dependent)
• 0.75rem = 12px — common for small/caption text
• 1.25rem = 20px — common for subheadings
• 2rem = 32px — common for section headings

Por que usar conversores CSS?

Converter manualmente entre formatos de cor é tedioso e propenso a erros.

• Instant results — paste a value and get the converted output immediately, no formulas needed.
• Copy-ready output — every result includes a one-click copy button with properly formatted CSS syntax.
• Color preview — see a live swatch of the converted color to visually confirm accuracy.
• No installation — works in any browser, on any device. No extensions, downloads, or signups.
• Developer-friendly — shareable URLs with pre-filled values for easy team collaboration.

Common CSS Conversion Workflows

• Design handoff: Figma and Sketch export colors as HEX. Convert to RGB or HSL if your codebase uses those formats.
• Dark mode generation: Take your light-mode HSL palette, adjust lightness values, and convert back to HEX.
• Accessibility checks: Convert colors to RGB to calculate contrast ratios using the WCAG luminance formula.
• Legacy migration: Convert pixel-based layouts to rem-based responsive systems during refactors.
• Cross-browser debugging: Quickly convert colors to match your source code format.
