Convert any color format instantly. Automatically detects HEX, RGB, RGBA, HSL, HSLA, HSV, CMYK, and named CSS colors, producing complete format exports, Tailwind 50-950 palette scales, and accessibility vision simulations.
Standard trichromatic human color perception.
Green cone deficiency. Greens appear brownish-yellow.
Red cone deficiency. Reds appear darker and brownish.
Blue cone deficiency. Blues appear greenish, yellows light grey.
Complete lack of color perception (grayscale monochromacy).

Authoritative standards, practical benchmarks, and best practices.
Designers receive brand guidelines in HEX. JavaScript canvas APIs want RGB. CSS developers increasingly prefer HSL for theme variables because adjusting --primary-light is one line. A converter eliminates manual lookup tables.
When pasting from Photoshop or Figma, watch for alpha channels. RGBA and HSLA include opacity. Standard HEX is six digits without transparency, eight digits with alpha on some platforms.
Straightforward answers regarding color converter calculations, platform limits, and data privacy.
The tool automatically detects 3-digit and 6-digit HEX, 8-digit HEX with alpha, RGB and RGBA, HSL and HSLA, HSV/HSB, CMYK, and all 148 standard CSS named colors like tomato, rebeccapurple, and midnightblue.
No. HEX and 8-bit RGB represent identical 24-bit color data using different numerical bases (hexadecimal base 16 vs decimal base 10). The conversion is mathematically exact and lossless.
The generator creates a 10-step tint and shade scale modeled on Tailwind CSS design tokens. Steps 50 to 400 are tints mixed with pure white, step 500 represents your base color, and steps 600 to 950 are shades mixed with black. You can copy individual hexes or the full JSON configuration object.
The accessibility panel simulates Deuteranopia (green blindness, ~6% of males), Protanopia (red blindness, ~2% of males), Tritanopia (blue blindness, <0.1%), and Achromatopsia (monochrome vision) using standard transformation matrices.
Type or paste your CMYK values in the format cmyk(76%, 47%, 0%, 4%) or cmyk(76, 47, 0, 4). The converter automatically calculates the corresponding RGB, HEX, and HSL equivalents.
Yes. Both RGBA (e.g. rgba(59, 130, 246, 0.8)) and 8-digit HEX codes (e.g. #3B82F6CC) preserve the alpha channel, outputting both transparent and opaque variations.
