The reason why the required paint color paste cannot be called:
1) The content of titanium dioxide is inappropriate (colors with poor hiding power cannot be displayed).
2) Improper choice of paint color paste (some colors cannot be replaced by other color pastes).
3) Color migration.
Unable to call out the required paint color paste color solution:
1) Choose a coating with appropriate titanium dioxide content.
2) Choose paint color paste with good compatibility.
