// Add this script to a cube prim and add "Listen Palete" script to another Object.
// You can resize and stretch the cube, the way you want, to make it look like a color palette.

In order for the above script to work as the original some corrections should be added.

Replace:

llSay(0,"Color: "+_vector);

with:

llSay(4,_vector);

Replace:

touch_start

with:

touch
