Well yeah, it is definitly possible without any array.

The code I gave you can be easilly be scaled for 3 or more variables. I’m atually using something really similar to send the color of each LEDs in this porject: [A universal ambilight](https://discourse.processing.org/t/a-universal-ambilight/1962). And it is way more than 3 variables 🙂
