# Color.fromARGB constructor

const Color.fromARGB(int a, int r, int g, int b)

Construct a color from the lower 8 bits of four integers.

- `a` is the alpha value, with 0 being transparent and 255 being fully opaque.
- `r` is red, from 0 to 255.
- `g` is green, from 0 to 255.
- `b` is blue, from 0 to 255.

Out of range values are brought into range using modulo 255.

See also fromRGBO, which takes the alpha value as a floating point value.

## Implementation

    const Color.fromARGB(int a, int r, int g, int b) :
      value = (((a & 0xff) << 24) |
               ((r & 0xff) << 16) |
               ((g & 0xff) << 8)  |
               ((b & 0xff) << 0)) & 0xFFFFFFFF;
