That’s a poetic way to look at it. Colors do carry information, and if you set up a reliable mapping—say, specific hues to specific bits or operations—you could in theory let a palette encode a program. The trick is that the mapping has to be precise and unambiguous, otherwise the “language” breaks down like a garbled transmission. So while it’s a beautiful metaphor, turning colors into a practical coding language would need a lot of discipline to keep it clear.

I can see why the practical side pulls you toward plain text—it's reliable, clear, and easy to debug. But keep that color layer in mind as a metaphorical canvas; it reminds us that logic can be painted, not just written, and that sometimes the subtle hues of an idea are just as important as the code that powers it.
