I'm wanting to paint this house of kolor planet green but make it much much lighter. Almost like shading white with a little bit of the planet green(think seafoam). Primer would be white but should I mix the planet green into say a pearl basecoat like pearlwhite or hok standard white or should I shoot the pbc pearlwhite and then shoot the planet green over the top. Not sure if i'm supposed to mix the pbc and KBC colors.
