Boysen Thalo Green LTC is a concentrated, water-based acrylic tinting paint (LTC stands for Latex Color) designed to be mixed with Boysen water-based paints, such as Permacoat Latex or Healthy Home, to create a range of pastel to medium Thalo Green shades. This colorant is user-friendly, disperses easily, and helps achieve even finishes for both DIY and professional painting projects, though specific color suitability for exterior use should be checked.
