    Color Guide

    Understanding Color Models

    • HEX: #RRGGBB format, the most commonly used in web development
    • RGB: Combines Red, Green, Blue in the 0-255 range
    • HSL: Represents color through Hue, Saturation, and Lightness
    • HEX and RGB express the same colors in different formats
    • HSL is the most intuitive as it matches how humans perceive color

    Color Selection Tips

    • Ensure sufficient contrast ratio between text and background
    • WCAG requires a minimum contrast ratio of 4.5:1 for normal text
    • Use accessible color combinations that consider color blindness
    • Limit brand colors to 2-3 primary colors for consistency
    • Apply color theory (complementary, analogous) for harmonious palettes

    Cake Toolbox & this page

    Cake Toolbox is K-K’s free web utilities collection at k-k.page. Where possible, tools run in your browser to reduce unnecessary data transfer; pages that call AI or external APIs explain what is sent. Calculator and converter outputs are for reference only—not legal, tax, financial, or medical advice.

    If something looks wrong, email us with the page URL. Many sites offer similar widgets; we aim to add clear context, limitations, and safe-use notes—not just the bare UI.

    Is my input stored on your servers?

    It varies by tool—read the notice on this page. Many converters and generators run fully client-side.

    Can I use this commercially?

    You may use it for personal or work reference. Uses that harm site operation (e.g. resale, abusive automation) may be restricted under our Terms.

    Where do I report bugs?

    Use /contact or ilinyion@gmail.com with the page URL and steps to reproduce.
