How to Use Color Converter
- 1Pick a color using the visual color picker or type a value into the HEX (`#8B5CF6`), RGB (`139, 92, 246`), or HSL (`258, 90%, 66%`) input fields.
- 2All other color representations update instantaneously as you edit any field.
- 3Check the live color swatch along with its relative luminance and WCAG contrast ratio against white and dark text.
- 4Click 'Copy' next to HEX, `rgb()`, or `hsl()` to copy the exact CSS string.
Key Features & Privacy
- ✦Bi-directional mathematical conversion across HEX (3-digit and 6-digit), RGB (`0–255`), and HSL (`H: 0–360, S: 0–100%, L: 0–100%`).
- ✦Strict input validation that highlights out-of-range RGB/HSL values or invalid hexadecimal characters.
- ✦Displays WCAG 2.1 contrast ratio against `#FFFFFF` (white) and `#080B18` (dark background) with AA/AAA pass badges.
- ✦Generates automatic complementary and analogous palette swatches.
Frequently Asked Questions
Does the HEX field accept 3-digit shorthand codes like `#09F`?
Yes. Both 3-character shorthand (`#09F` → `#0099FF`) and standard 6-character hexadecimal codes (with or without the leading `#`) are parsed and validated.
What happens if I enter `rgb(300, -10, 50)`?
RGB channels must be integers between `0` and `255`. The tool flags out-of-bounds values with an explicit validation message instead of silently producing wrong colors.
