Hex to RGB Converter

Hex is a 6-character shorthand (#FF5733) that represents the same color as RGB(255, 87, 51). Both encode red, green, and blue channels — hex uses base-16 notation while RGB uses base-10 values from 0-255. Hex is the standard in CSS and HTML, while RGB is common in design tools, image editing software, and APIs.

Split the 6-character hex code into 3 pairs (e.g., FF, 57, 33), then convert each pair from base-16 to base-10. For example: FF = 15*16 + 15 = 255, 57 = 5*16 + 7 = 87, 33 = 3*16 + 3 = 51. So #FF5733 = RGB(255, 87, 51).

RGBA adds an alpha (transparency) channel to RGB. The alpha value ranges from 0 (fully transparent) to 1 (fully opaque). Use RGBA when you need semi-transparent colors — for example, overlays, faded backgrounds, or layered UI elements. In CSS: rgba(255, 87, 51, 0.5) gives a 50% transparent orange.

Color rendering depends on each monitor's color profile (sRGB, DCI-P3, Adobe RGB), brightness settings, and calibration. An uncalibrated display can shift colors noticeably. For accurate color work, use a hardware-calibrated monitor and design within the sRGB color space for maximum consistency across devices.
