In　this　paper,　a　new　scheme　for　generating　a　wide　gamut　of　structural　colors　on　the　thin-film-stack-based　(TFSB)　substrates　is　proposed.　The　TFSB　surfaces　consist　of　titanium/random　gold　nanoparticles　(AuNPs)　and　titanium/　random　gold　and　copper　nanoparticles　(Au+CuNPs),　which　can　trigger　more　resonance　absorption　and　widen　the　color　gamut.　The　electric　fields　in　two　designed　structures　are　simulated,　and　the　results　showed　that　the　random　distribution　of　AuNPs　and　Au+CuNPs　enhance　the　uniform　local　surface　plasmon　resonance　(LSPR)　response.　This　enhancement　is　crucial　in　broadening　the　coverage　of　the　reflection　spectrum,　which　enables　the　generation　of　a　wide　range　of　colors,　including　green　and　red.　The　influence　of　laser　parameters　on　the　color　of　TFSB　substrates　and　tested　their　durability　in　terms　of　time　is　analyzed.　Finally,　a　color　palette　and　made　structural　color　patterns　on　TFSB　by　nanosecond　pulsed　laser　are　prepared.　The　proposed　new　scheme　can　be　easily　fabricated　by　magnetron　sputtering　without　requiring　additional　procedures,　which　can　open　new　perspectives　in　plasmonic　colors.　This　work　demonstrates　that　the　promising　potential　of　methods　in　creating　a　wide　color　gamut　on　metallic　surfaces.　Additionally,　it　serves　as　a　means　to　store　information　for　the　preservation　and　protection　of　traditional　cultures.　A　new　scheme　for　generating　wide　gamut　structural　colors　on　the　thin-film-stack-based　(TFSB)　substrates.　The　random　distribution　of　AuNPs　and　Au+CuNPs　enhance　the　LSPR　response,　which　is　crucial　in　generating　of　a　wide　range　of　colors.　The　proposed　new　scheme　can　be　easily　fabricated　by　magnetron　sputtering　without　requiring　additional　procedures,　which　can　open　new　perspectives　in　plasmonic　colors.　image
