[Linux 常見問題] ANSI Color Specific RGB Sequence Bash

 Source From Here

Question
I know that in bash terminals a reliable way to change color is using ANSI escape sequences. For example:

# echo -e "\033[0;31mbrown text\033[0;00m"

should output

brown text (in brown)

Is there a way to output color using a specific RGB set with ANSI? Say I want bright red:

# echo -e "**\033[255:0:0m**red text\033[0;00m"

Does this sort of thing exist?

HowTo
This will work

# echo -e "**\033[38;2;255;0;0m**red text\033[0;00m"

format:

"\033[38;2;R;G;Bm"

* R is your RED component of your RGB
* G is your GRREN component of your RGB
* B is your BLUE component of your RGB
