play sound based on objects color

I'm thinking this would be a very simple script, but since I'm still a bit new to scripting, im not sure of values, names, etc, but I'll make it as easy to understand as possible.

Bassicly, I'm using if statements to do this. What I have is an object with:

touch1(){
changeColorBy(10);

I need something like:

if color = 10 then play sound1
if color = 20 then play sound2
if color = 30 then play sound3
etc etc

any help would be appriciated

Not sure which parts are the question. One can get the color of an object (or one face of an object) with llGetColor... which will return a vector of floats corresponding to RGB values. Then it's a question of how to map the RGB colorspace into the fixed set of sounds, so you can play them, probably with llPlaySound() (although llLoopSound(), llTriggerSound, or llTriggerSoundLimited() might be appropriate, depending on the desired effect).

Maybe, if there are just three sounds, you find which of the Red, Green, and Blue color values is the largest, and choose based on that. Or you add together the floats and play a sound based on total brightness (< 1.0 is the "dark" sound, > 2.0 is the "bright" sound, otherwise it's the "medium" sound). Or something.
