在线免费颜色格式转换器

Split the 6-digit hex into three 2-digit pairs and convert each from hexadecimal to decimal: #FF5733 → R=FF=255, G=57=87, B=33=51 → RGB(255, 87, 51). This tool converts all formats simultaneously.

HSV (Hue, Saturation, Value/Brightness) is used in Photoshop and most design software. HSL (Hue, Saturation, Lightness) is the CSS standard. Both use 0–360° hue but define the second two parameters differently. Pure colors at HSV(H, 100%, 100%) appear at HSL(H, 100%, 50%).

CMYK (Cyan, Magenta, Yellow, Key/Black) is the color model used in print production. Provide CMYK values to print shops and in design files exported for printing. Screen RGB colors may look slightly different when printed in CMYK.

CSS defines 140 named colors from "alice blue" to "yellow green." Common ones: red, coral, tomato, orange, gold, lime, green, teal, cyan, blue, indigo, violet, pink, white, black, gray. Enter any name to see its HEX and RGB values.

Yes. Enter RGBA (255, 87, 51, 0.5) or 8-digit HEX (#FF573380) to include alpha. The tool shows all transparent format equivalents including HSLA.
