Different colors in console string

/ Published in: C#
Save to your folder(s)
This is way to get different fg and bg colors inside 1 string. You provide escape like characters to define colors.

This is a fg of #rRed #xand now we're back to normal.
This is a bg of $bBlue#x and now we're back to normal.
I can combine fg & bg#r$bcolors #xalso.
