I'm trying to [K08]Yellow[K04]Red[KEND]Yellow
Using just a [K] will do the trick unless a Number follows the code, which is the problem I'm having, which cannot be worked around by means of scripts. (Im writing a C bot to show colors etc.. not important...)

Using [O] may end other control codes
Using [K99] will put the color back to the color of the line, but it does not RESUME the previous [K08] like it should.

I think I'm asking for nested control codes?
