DIY dark gray mix for a projection screen

This mix can be close to black if you need it to be you just need to have a high lumens projector of 3000 lumens and up. I mixed half of the pearl with half black onyx and if you want a darker screen mix just add more black to your liking. I also added some water to thin out the paint because it's real thick when your barely pouring it out. . I hope this mix helps someone who is beginning . I used a Epson 5450 4200 lumens projector 1080 p.
