Very true for the real world. For Arduino sketches though, it's pretty simplified. OO design here would likely be overkill. For a sketch file, you essentially have two methods that execute: setup and loop.
In setup, you initialize your variables, pins, etc. In loop, you put in the code that will repeatedly execute in a loop.
Considering the stated objectives, I'd solve the problem in the loop code like so:
* Read the pressure sensor value and convert that to a decimal value between 0 and 1.
* Generate random values for red, green and blue LEDs and store those values into three variables.
* Multiply each of those three variables by the converted pressure sensor value.
* Write the three values to the RGB LED output pins.
