Every step of the maths
How HEX becomes ARGB
Each step shows the values for the color above, as the converter computes them.
- Start Hex digits
#D3AF37 - Back 8-bit channels
each pair of digits read as a byte211 175 55 - Then Alpha first
0x AA RR GG BB0xFFD3AF37
ARGB
About ARGB
Android, Jetpack Compose and Flutter write a color as 0xAARRGGBB: alpha first, then red, green and blue, as in Color(0xFFD3AF37). FF is opaque, and 80 is about half.
How this page writes it
- Reads 0x literals, Color(…) and eight hex digits, and writes 0x with capital letters.
Watch for
- CSS puts alpha last: #D3AF3780 in CSS is 0x80D3AF37 here. Swapping the order is the most common mistake.
