The CSS color module defines colors, color types, color blending, opacity, and how you can apply these colors and effects to HTML content.
The color syntax converter below shows the values of the currently selected color in red-green-blue (RGB), hexadecimal (HEX), hue, saturation, and lightness (HSL), and hue, whiteness, and blackness (HWB) CSS color formats. All the RGB, HEX, HSL, and HWB color values here, while written differently, represent the same color value.
Selecting a color via the color picker and an opacity via the slider updates the RGB, HEX, HSL, and HWB values. When you choose a new color or opacity value, the color of the background and the slider update via the CSS properties
