Unfortunately it looks like Io sequences (strings) only convert single (alpha) character escape codes like \n or \t.
So (for now) this maybe the only workaround:
27 asCharacter .. "[0;34;40mHi!" println
题
Is there a special trick to getting Io to switch the colors of terminal text? In Python I can run
print "\033[0;34;40mHi!"
and get a blue "Hi!".
In Io,
"\033[0;34;40mHi!" println
seems to have no effect.
