fix: use printf instead of echo for ANSI escape sequences

Replaced echo with printf for lines containing ANSI color codes
to improve portability across different shells.

Fixes Codacy warnings:
- Line 44: echo → printf for color formatting
- Line 45: echo → printf with proper format string
- Line 51: echo → printf in loop with format placeholders

The echo command's handling of escape sequences is not
standardized across shells. printf is the portable solution
and is recommended by POSIX for formatted output.
