Android mostly use the RGB color model encoded as a 32-bit unsigned integer to represent colors,
where each channel use 8 bits (1 byte) with a value between 0 and 255.
ARGB values are typically expressed using 8 hexadecimal digits,
with each pair of the hexadecimal digits representing the values of the Alpha, Red, Green and Blue channel, respectively,
0xFFFF0000 for opaque red.
A color model is an abstract mathematical model describing the way colors can be represented. RGB in a common color model used on Android.
