Liquid metals are promising multifunctional materials, but their single-colour physical appearance limits their applicability. There are several methods to endow liquid metals with colour and fluorescence, and although breakthroughs have been made in controlling their optical and interfacial properties, more work is needed to refine the synthetic strategies, better understand the coloration effects and enable the applications of colourful liquid metals.
