The TextsFlix Color Code Converter & WCAG Contrast Checker is an all-in-one color management utility engineered for web developers, graphic artists, and UI/UX designers to seamlessly convert, tweak, and test colors across HEX, RGB, RGBA, HSL, HSLA, and CMYK formats. Whether you need to translate an RGB color from CSS into a CMYK printing palette, grab CSS custom property variables, or ensure your UI typography meets strict web accessibility guidelines, this tool does it with zero delay.

Equipped with interactive RGB and HSL channel sliders, an embedded browser pipette color picker, and curated modern UI palettes, you can visually sculpt colors and observe synchronized numeric values update live across every color model simultaneously.

Key capabilities include:

• Universal Color Conversion: Instant bidirectional conversion between HEX, RGB (0-255), RGBA with alpha transparency, HSL (hue, saturation, lightness), HSLA, and CMYK (cyan, magenta, yellow, black).
• WCAG 2.1 Contrast Testing: Test your color's contrast ratio against pure white (#FFFFFF) or dark slate (#0F172A) backgrounds with live Level AA and Level AAA pass/fail metrics.
• Dual Interactive Sliders: Control individual Red, Green, and Blue channels or fine-tune Hue degrees and Saturation percentages smoothly.
• Curated Preset Palettes: Quick-select electric indigo, emerald mint, sunset crimson, amber gold, and obsidian slate swatches.
• CSS Variable Generation: Copy production-ready CSS custom properties (--color-primary: #...) with one click.
• 100% Client-Side Privacy: Zero server communication — runs locally inside your browser tab.

Web Content Accessibility Guidelines (WCAG) 2.1 establish standards for making digital web content accessible to individuals with visual impairments, color blindness, or aging vision. Insufficient contrast between foreground text and its background is one of the most common accessibility failures on the internet.

Our integrated contrast checker automatically calculates the luminance ratio between your chosen color and background, providing instant compliance verification:

• WCAG Level AA (Normal Text): Requires a minimum contrast ratio of 4.5:1 for body text under 18pt (or bold under 14pt).
• WCAG Level AA (Large Text): Requires a minimum contrast ratio of 3.0:1 for headings and large text (18pt+ or bold 14pt+).
• WCAG Level AAA (Normal Text): The enhanced high-accessibility threshold requiring a minimum contrast ratio of 7.0:1.
• WCAG Level AAA (Large Text): Requires an enhanced minimum contrast ratio of 4.5:1 for prominent headings.

Use the live test toggle to test readability on both light and dark backgrounds to ensure your buttons, hyperlinks, and body copy pass international accessibility audits.

What is the difference between RGB and CMYK?
RGB (Red, Green, Blue) is an additive color model used for electronic screens (monitors, smartphones, TVs). CMYK (Cyan, Magenta, Yellow, Key/Black) is a subtractive color model designed for physical ink printing.

What is HSL and why do designers use it?
HSL stands for Hue (0-360 degrees on the color wheel), Saturation (color intensity 0-100%), and Lightness (brightness 0-100%). Designers favor HSL because adjusting lightness or saturation produces natural tints, shades, and monochromatic color palettes without altering the core hue.

What contrast ratio is required for WCAG compliance?
Standard WCAG Level AA compliance requires a contrast ratio of at least 4.5:1 for normal body text and 3.0:1 for large headings. Stricter Level AAA compliance requires 7.0:1 for normal text.

Can I test colors with opacity or transparency?
Yes. The tool supports 8-digit HEX codes (e.g. #6366F180) and RGBA/HSLA with alpha values from 0.0 to 1.0.
