What color formats does Color Studio support?+
You can convert between HEX (#RRGGBB), RGB/RGBA, HSL/HSLA, and OKLCH — the perceptually uniform format used in modern CSS. Four panels sit side by side; edit any one and the others update instantly.
Is my data sent to a server?+
No. All parsing and conversion run in your browser. Color values never leave your device.
What is OKLCH?+
OKLCH expresses color as lightness (L), chroma (C), and hue (H). It is designed for predictable adjustments — for example, changing lightness without skewing hue — and is supported in current browsers via CSS Color Level 4.
Why do HEX and RGB values differ slightly from OKLCH round-trips?+
Conversions go through sRGB and OKLab math with rounding at each step. Tiny differences (±1 on a channel) are normal and still produce visually identical colors.
Can I pick a color visually?+
Yes. Use the native color picker under the preview swatch. It updates HEX, RGB, HSL, and OKLCH together.
Does it support transparency?+
Yes. Use rgba(), hsla(), 8-digit HEX (#RRGGBBAA), or OKLCH with an alpha slash (oklch(L C H / 0.5)). The preview shows a checkerboard behind semi-transparent colors.
Is Color Studio free?+
Yes. It is free, requires no signup, and works offline after the page loads.
