Social color has to survive the feed
A color palette for social media faces constraints that brand guidelines rarely anticipate. Instagram compresses images and shifts color slightly. TikTok overlays white text on everything. YouTube thumbnails render at tiny sizes next to dozens of competitors. Your palette needs enough contrast and saturation to remain identifiable after compression and scaling. That usually means fewer colors with more deliberate lightness separation rather than a wide, subtle range that flattens to mush at 120 pixels wide.
