Color

We use ANSI escape code color in other to display 3-bits, 4-bits, 8-bits and 24-bits of color on the console/terminal window. In the future, we may use 8-bits. The table below is the 3-bits and 4-bits of color ANSI escape code.

Real implement destination: color.h

Some example for 4-bits color:

Color	ANSI Color	Color	ANSI Color
Bright Black	\033[1;90m	Bright Blue	\033[1;94m
Bright Red	\033[1;91m	Bright Magenta	\033[1;95m
Bright Green	\033[1;92m	Bright Cyan	\033[1;96m
Bright Yellow	\033[1;93m	Bright White	\033[1;97m

Cursor control

The cursor is manually controlled by using ANSI escape code.

Implementation

Pixel

Pixel has three uint8_t attributes, r, g, and b, which stand for RED, GREEN, and BLUE, respectively.

class Pixel {
    uint8_t r, g, b;
};

Real implement destination: Pixel.h, Pixel.cpp
