I’m all about the science of color—teal does hit the calm vibe while coral screams attention, so I do test A/B to see what actually pulls the thumbs up. But honestly, half the time my mood decides the palette on the fly, and those spontaneous color bursts are the ones that feel alive and keep the comments flowing. So tweak a few hues, run a quick split test, and let the engagement data decide, but keep that gut‑feel spark in the mix—you never know when a sudden pastel pop might just break the algorithm’s monotony.
