# Rust Color
Rust Color is a terminal color rendering library,
thats supports 3/4 bit colors, 8 bit colors, 24 bit color
rendering output, compatible with windows.

## ANSI Escape Codes for Terminal Graphics
The ANSI escape code standard, formally adopted as ISO/IEC 6429, defines a series of control sequences.
Each control sequence begins with a **Control Sequence Introducer** (CSI), defined as a scape character
followed immediately by a bracket: **ESC[**.
