LED-Matrix - Interrupt equalizer for a single command

hey all!

currently working on small led-matrix , working way want.
i start processing sketch analyzes music playing on computer , sends data nonstop led-panel.
something similar this:

my processing sketch sends 7 bytes arduino every cycle (for example: 1202014)
the arduino receives bytes code:

code: [select]

void readserial(){
  if (serial.available() > 6) {
      bar1 = serial.read()-48;
      bar2 = serial.read()-48;
      bar3 = serial.read()-48;
      bar4 = serial.read()-48;
      bar5 = serial.read()-48;
      bar6 = serial.read()-48;
      bar7 = serial.read()-48;
  }
}
this working far.
but want able change color while animation running.
how can make sure these commands won't mix up?
i want send "c255000100" (color,r,g,b) arduino.

any ideas?

thanks

you have establish protocol. define commands display update, color change , every other action want arduino execute. commands can single characters (fast) or complete words (better human readable), decide. make more robust, define start character , end character complete message.
