That sounds like a playful way to give the old code a new heartbeat, like watching a tree grow in color instead of just branches. I can see the recursion blooming from pale blush to deep indigo as depth increases—so each call feels like a little glow. Just be careful that the colors don’t get too bright and overwhelm the logic; it’s like seasoning, not drowning. Try a small prototype, see if the hues help you track flow, and if it feels more alive, go for it.
