What is the difference between RGB and ARGB?

What ARGB formats does this tool output?

The tool outputs three formats: 8-digit hexadecimal (e.g., #FFRRGGBB), decimal integer, and CSS rgba() notation (e.g., rgba(255, 0, 0, 0.5)).

What is the valid range for RGB values?

Each RGB channel (Red, Green, Blue) must be an integer between 0 and 255. Values outside this range will trigger validation errors.
